We’ve upgraded lemmy.world to 0.18.1-rc.1 and rolled back that upgrade because of issues.
(If you had posted anything in those 10 minutes between upgrade and rollback, that post is gone. Sorry!)
The main issue we saw is that users can’t login anymore. Existing sessions still worked, but new logins failed (from macos, ios and android. From linux and windows it worked)
Also new account creation didn’t work.
I’ll create an issue for the devs and retry once it’s fixed.
Edit Contacted the devs, they tell me to try again with lemmy-ui at version 0.18.0. Will try again, brace for some downtime!
Edit 2 So we upgraded again, and it seemed to work nicely! But then it slowed down so much it was unuseable. There were many locks in the database. People reported many JSON errors. Sorry, we won’t be on 0.18.1 any time soon I’m afraid…
Thank you for the transparancy!
I love post like this, another reason of why this instance is so good
Thanks for all your hard work @[email protected]. It’s not easy!
As any engineer who does ops can tell you - you did the right thing - the solution is always to roll back, never force a roll forward, ever.
We should totally do pre and post update parties though. Even if the update fails we can have an excuse for drinks and a fun thread.
Although since we seem to be rolling more than a ship in a storm, I think a proportion of lemmings would end up hospitalised for alcohol poisoning.
Both Dessalines and Nutomic have been working their butts off to get 0.18.x ready for the Reddit API changes. Huge hopes they can pull through!
Dessalines:
Nutomic:
Yeah they’ve been hard at work all month. But it’s also okay if things aren’t ready in time. Most of the people who matter are already here.
Maybe we will blow up soon, maybe later, but the quality of content here is sufficient to drive growth regardless of whether or not we get the prophesized huge migrations from reddit
It’s adequate the way it is now. They should hold off on any major upgrades until after the next batch of new users come in. Lemmy breaking during that period would be far worse then missing some updates and new features.
Agreed. I’m here to stay with the content from the last couple weeks. 3 day poop embargoes alone is worth it. And recognizing users because the community is still small enough is SO different from they who shall not be named.
Oh god, so much coffee… it’s also thrilling to grasp a sense of what’s going on under the hood of such big social networks at a development level (not like I could understand it, but it was very interesting to see twitter’s recommendation algorithm being open-sourced)
is that users can’t login anymore
Ouch, that’s bad :(
Thank you for your work, as always :)
I mean that’s a Tuesday on Reddit lmao.
Thanks for the hard work /u/ruud, we’ll get there
appreciate the transparency. how are things looking in the back in lemmy.world (server wise)? will we get to a point where it wont require complete rollbacks on the state when a botched update gets rolled out?
Not having to do a database rollback is a really, really hard problem to solve, and it would almost certainly need to be on the Lemmy developers side, not the server owner’s side. And if I’m them, that’s a low priority issue, and probably not something I even think about until 1.0.
Basically, they write code that says what to do in the event of a database version change. Usually this only handles upgrade cases, because that’s what happening most of the time. One example of something you might do in a db upgrade is let’s say you had a column where the data type was only numbers, but now you want to allow any alphanumeric character for some reason. You could have a line of code that converts the number to a string.
Okay, but now you need to go back to the previous version. Okay, your db change code runs, but it’s the old version of the db change code, not some new version that you wrote. You unfortunately didn’t have a crystal ball when you wrote this code and couldn’t predict that you were going to change the data to strings, so you didnt write code to change it from a string to a number.
This is why most software doesn’t support downgrades unless you wipe first. For example, if you updated your aging MacBook to the latest Mac OS version, then realized it slows down your laptop too much, you can only go back if you first wipe your laptop in the process. So it’s just easier to just take a snapshot before an upgrade and revert to the snapshot if it fails. Some folks will even do “scheduled maintenance” time during the upgrade in which the whole system goes down for a short time so they don’t have to risk losing data that happened after the snapshot.

We have one! This was tested on a test instance before
Cool, great minds think alike 😁
Yeah we have a test instance, but not sure if we could test with this kind of load…
There are already 3 test instances where devs push updates before going live, but:
- if not many people go there test, they won’t catch all the bugs.
- in this specific case, admins are trying to push a new release candidate (that is not officially released yet) because some people are stuck with mobile apps that don’t work anymore on the version we have now.
Just curious, why are we updating now instead of waiting for the proper 0.18.1 release?
Because of a few things, really anoying bugs and the Jerboa app not working properly with older versions
Federation is completely borked with .18 servers. Its very difficult for us to interact with https://lemmy.ca in any way: subscribing, upvoting, comments, posting… its all bugged.
Its maybe not that big a deal because Lemmy.world “has the most users”, so in some regards its https://lemmy.ca’s loss but… we need to restore reliable federation… especially before the July 1st rush IMO.
The .17 to .18 upgrade is basically a soft-defederation event, because of whatever this bug is between the two versions.
Ah that explains it. Someone posted a cool photo to my community from lemmy.ca but didn’t interact further. Looks like my comment didn’t even show up on their end.
Anyway, thanks to everyone working on the issue. I know these things aren’t easy.
I’m subscribed to lemmy.ca and programming.dev, both of which are .18 now. Feels kinda bad losing access to those communities while this issue is getting worked out…
Reasons I can think of:
-
The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.
-
Sorting is broken pre 0.18, new posts keeps flowing in.
-
Performance improvement by removing web socket from lemmy. (which fixes 2, which is why 1. happens)
Jerboa works fine with lemmy world, it just gives a warning and crashes on occasion. Not an issue to use it though.
Yes, if you are already logged in. If you are not logged in, or get logged out you will not be able to log back in until the server version is above 0.18
That sounds like Bethesda’s definition of “works fine”
It just works, it just works…
It works fine if you apply unofficial patch!
“crashes on occasion”
Unfortunately, the occasion seems to be at least once every five minutes for me. thisisfine.jpg This is not fine and definitely a major issue. Especially as we get closer to July 1. After this news from lemmy.world, I will have to switch, probably to Connect, until Sync arrives.
Have you tried this fork? https://lemmy.ca/post/899342
For me at least, I’m unable to change the community scope or sorting method. The only thing I can use Jerboa for is “local” and sorted by “active”. It isn’t totally unusable, but I would much rather be able to switch to subscribed and hot.
I had the same bug. A full restart of my phone seems to have fixed it.
Unfortunately that didn’t work for me. Thanks for the idea, though. I’m sure it will work for some. I suspect that if I wiped the app and set everything back up it might work, but that’s more than I’m willing to do at the moment and I can live with the inconvenience for now.
Alternatively, you can try this fork: https://lemmy.ca/post/899342
As a new user I tried logging in on Jerboa and it says the server must be on 0.18 and refuses the login.
Have you tried this fork? https://lemmy.ca/post/899342
Thanks for the link. I knew could side load an older version, I just wanted to be lazy and use something on the play store. I’m trying out several clients right anyway.
The latest update of jerboa did not let me browse all communities. I had to sideload a previous version.
Well you’re a lucky one. Jerboa has been unusable for me and other folks post v0.34 since the first rc release of 0.18. I finally managed to downgrade to 0.34 and login after lots of black magic. It used to crash instantly, even on 0.34.
That being said, good luck to lemmy.world admins and thanks a lot for the open comms !
That is absolutely not “fine”.
It won’t let me log in, so no, it doesn’t “work fine.” But I have six other apps for Lemmy, so I’m not worried. It’ll all be sorted eventually.
Alternatively, you can try this fork: https://lemmy.ca/post/899342
With the last couple updates jerboa has got to a point that I probably won’t even move to sync when it comes. I’m pretty happy with it. But if Lemmy Is Fun ever happens, I’m out.
I’m of a similar mind: I’m happy with Jerboa, yet also looking forward to Slide.
Try wefwef.app on mobile
(no I’m not a bot account shilling I just really like the app)
I’m sold. 😊 I did need to try a couple of times to figure out I needed to swipe left to reply to a comment, though. But it looks good, works well, and I’ll get used to the quirks.
If there was a way to adjust the font sizes it would be 100% perfect. Damn! I’m surprised I hadn’t heard of it before. Thanks internet stranger!
Nice and thanks!
Question: Where’s the edit button? I can’t find it.
It’s an open issue on their github (https://github.com/aeharding/wefwef). Will probably be available soon, the development seems to be fast - I got two updates in a single day. Also tagging @[email protected]
Oye spaceduck, tas rechulo y lo sabes. !tip 12
Why the hell does Jerboa even limit support to 0.18? That’s so stupid.
The latest version only supports 0.18 because the backend works differently. Older versions of Jerboa support older backends of lemmy.
Connect for Lemmy works better.
Is it open source?
I don’t know but I installed and older version of Jerboa from F-Droid store. I couldn’t login from the most recent version of Jerboa because of this so it was pretty much useless for me. Working fine so far.
Likely because Jebora is written as a side project of the devs of lemmy so it’s always going to be cutting edge
I understand that. I’m not complaining about the quality. I’m just confused from a technical perspective why it doesn’t support rollback or older server versions in the event of…this.
Fixing the issues with posts appearing and scrolling the page the backend needed some pretty drastic rewrites. I’m not super familiar, but from what I’ve seen of the code, it would be a decent amount more work to support both versions.
Would it have been worth it? Yes, but it wasn’t anticipated that devs would stay on 0.0.17 for more than a day or two. With the time it takes for app stores to update, servers would have been updated before lemmy 0.0.45 was updated for the vast majority of users. At most, it would be a day or two instead of a week or two.
The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.
Even that won’t work, because Jerboa initially tries to connect to lemmy.ml which is running 0.18, which older versions of Jerboa aren’t compatible with. The app just crashes instantly without giving you the opportunity to log in to your instance.
The old version is working fine for me, I had the crashing issue, but reinstalled and it’s working now

UI at 0.18.0 and backend at .1rc1
Yep we tried bringing both the UI and the backend to 0.18.1-rc1 but that gave issues. Lemmy devs told us to try this combination and that seems to work. 🤞
I suspect there will be a large influx of new users in two days, and that having Jerboa not working on .world might cause a few issues
For example the frontpage is no longer being constantly filled with random posts when you set the filter to “active” or “top day”.
Just curious, why are we updating now instead of waiting for the proper 0.18.1 release?
A Release Candidate is supposed to be past beta testing already and in a state of no major bugs.
Cause if you are on the homepage for a little bit new post start pushing the old post down and it keeps doing it. something about websockets that 18 fixes it. im assuming the admins want to get it out now so people can stop complaining about it. i get it though just wait for the 18 instead of the rc-1 but users are impatient and can’t wait for sh*t!
UI: 0.18.0 BE: 0.18.1-rc.1 👍
seems to be working for me, I was already logged on
Suddenly my Jerboa won’t change from local and I can’t change the sort. Not sure if this is related, but it was working fine yesterday after I updated the app. But no longer this morning.
What you’re describing is an issue introduced with Jerboa 0.0.36-alpha and has been fixed in today released 0.0.37-alpha.
Oh nice
Mine randomly quit working a few days ago. All I get is a blank screen. I’ve switched to the website for now, though I need to look into the other app options. There are a couple more now.
Wefwef.app is pretty interesting. Its browser based and so far seems more stable to me than a lot of the current Android apps. Not sure what happened, but Jerboa and the like all have become nearly completely unusable with bugs and crashes.
Wefwef seems to unfortunately be lacking some very basic features tho.
Jerboa is extremely sluggish on my phone.

Try Thunder The Dev just now finished a fix which makes scrolling so much more enjoyable.
Mine’s been doing it since yesterday, on all instances.
There’s an annoying workaround, but you can change your default sorting in settings and relaunch. It’s getting stuck on whatever your default sorting is.
Me too, I am using Liftoff for now.
I am also trying out Liftoff
The UI and design looks nice but the chunky 12 fps scrolling is a bit annoying. I hope it’s gonna be better.Try the App Thunder The Dev solved the scrolling/memory issue there.
Do image downloads work? I noticed that doesn’t work on Liftoff (also done with Flutter)
Yea, downloading is the latest feature in the Dev-Build. Not sure if it’s released as I received it to test if a bug with scrolling is resolved.
Oh. Good luck with the next try!
I am glad I didn’t write my last post during the upgrade process.
Maybe next time, give a warning, or maintenance notice.
Thanks for trying though.
That’s just a pain point of using modern asynchrony software and will never go away
Thanks for the transparency. Maybe it’s a good idea to have a test instance and some test cases/validation done there before updating the main instance. This is a regular process in any software/tech company/stack.
Testing should never be done directly on the prod instance.
i think they tested it which worked fine, but it is totally different when there are users online
Correct there was a test instance and that worked fine but once the live instance was upgraded everything became very slow. Can’t really emulate that kind of load
Jerboa is almost unusable for me at the moment. A lot of crashes, pages not loading, messages not sending etc. But I know that’s inevitable at times. Restarting my phone seemed to make it worse. But I know you guys are on it! 👍
Liftoff is a much better app. I used Jerboa as well but found an alternative cuz it was pretty much unusable. Just dowload Liftoff’s latest apk and install
I am using it to, quite nice, it still miss some quality life features, but I am they will get to it.
Holy crap I just checked right now and Liftoff is on Playstore already!
I recommend you this web app
It is almost as functional as Jerboa and very impressive for a web app.
Already has a lot of what I liked about Apollo just in a web app, very cool!
It works unbelievable well.
Wow, awesome design!!!
I’m impressed as well, I don’t even like web apps, but God this looks amazing, and even better for me because I have an Android device and it has been ages since I used Apollo lol.
Currently rate-limited by Lemmy.world, per the dev. You might get a lot of red error boxes.
Why?
Too much traffic going through the app, as he explained it. I would try to link the post, but everything is so janky on both Lemmy.world and our wonderful Apollo clone that I can’t be bothered.
Too much traffic because it is an outstanding app, gotcha.
I just switched to it, Had tried jerboa, connect and liftoff and this one is by far my favorite
Yeah it has plenty of good features already!
How did you install it? I was using the app through the Google Playstore and for some reason the app was really unstable and buggy. I ended up installing the app from F-Droid and it is drastically better and much more stable.
