The server is proprietary and last I checked you can’t even turn off auto-updating or verify the binaries they push to you.

In the Ubuntu 20.04 package base, the Chromium package is indeed empty and acting, without your consent, as a backdoor by connecting your computer to the Ubuntu Store. Applications in this store cannot be patched, or pinned. You can’t audit them, hold them, modify them, or even point Snap to a different store. You’ve as much empowerment with this as if you were using proprietary software, i.e. none. This is in effect similar to a commercial proprietary solution, but with two major differences: It runs as root, and it installs itself without asking you.

• proprietary server (snap store), unlike flatpak
• snapd only allows one server (but it is foss so you could just patch it), unlike flatpak
• nonexistent security on snap store, multiple times malware, unlike flatpak
• no sandboxing without apparmor and specific profiles, so not cross platform, unlike flatpak
• the system apps are also requiring apparmor, so not cross platform
• they lack granular permission systems afaik
• they concur with flatpak, which is horrible as we need a universal packaging format, not 3
• seemingly no reproducible builds?
• no separation between all, opensource, verified repo, unlike flatpak
• they pollute the mount list with all the loop devices

And people complain abour resource usage etc, but that is just separating apps from the system. Flatpak does the same.

Research what happened to Upstart, Mir or Unity. It won’t take long until snap becomes one of them. Somebody at canonical seems to desperately obsess over having something unique, either as a way to justify canonicals existance or even in the hopes of making the next big thing. Over all these years they never learned that whatever they do exclusively will always fall short of any other joint efforts in the linux world, because they always lack the technical advances, ability/will to push it for a prolonged time and/or the non-proprietary-ness. So instead of collaborating like every serious linux vendor, they’re polluting their distro with half-assed, ever changing and unwanted experiments. They’re even hijacking apt commands to push their stupid snap stuff against the users intent. With the shengians they’re pulling Ubuntu cannot be relied on, and with that they’re sabotaging their own success and drive away any commercial customers that generate revenue.

Well, things like the fact that snap is supposed to be a distro-agnostic packaging method despite being only truly supported on Ubuntu is annoying. The fact that its locked to the Canonical store is annoying. The fact that it requires a system daemon to function is annoying.

My main gripes with it stem from my job though, since at the university where I work snap has been an absolute travesty;
It overflows the mount table on multi-user systems.
It slows down startup a ridiculous amount even if barely any snaps are installed.
It can’t run user applications if your home drive is mounted over NFS with safe mount options.
It has no way to disable automatic updates during change critical times - like exams.

There’s plenty more issues we’ve had with it, but those are the main ones that keep causing us issues.
Notably Flatpak doesn’t have any of the listed issues, and it also supports both shared installations as well as internal repos, where we can put licensed or bulky software for courses - something which snap can’t support due to the centralized store design.

Imma be honest. I never used Snap. I had left ubuntu long before they started rolling it out.

That said, hearing they redirect apt calls to snap instead feels – A bit too microsofty for my tastes

Like, when you use a flatpak (or even a snap!) in a non-ubuntu distro, you’re not forced to use it. And if the same package exists on both the repo and on flatpak/snap, you CAN choose to get it from any of the three sources. Forcing people into snap is weird and scummy.

I have heard that snap is slower than flatpak, but also that it can do some stuff flatpak cannot, but again, didn’t test enough to know it.

I hate snap, because their store is proprietary and i think forcing something with a proprietary store on you is microsoft level shit which is why i left in the first place.

Also i dont like being “forced”, theyre doing that a little with the apt install sometimes going to snap install

Personally I think for home users or niche there should be a snap less variant of this distribution with all the bells and whistles.

There is : Linux Mint

In addition to what’s already been said, Canonical have a history of starting grandiose projects and then abandoning them a few years later. See Mir, Unity, and Ubuntu Touch for examples.

For me it is partially the way canonical pushes snaps and forces it on to users. More so they are slow and the proprietary back end is a huge downside. Some snaps are know broken and cause more harm then good like the steam snap for example. Steam actively discourages users from even using it.

I would hate snaps a lot less if Ubuntu just stopped trying to force me to use them.

I think most people hate Snaps because Ubuntu is replacing .deb packages with snaps with no user prompt and that is a cardinal sin in Linux against the freedom and power of the user. Being “bloated” can’t help either when package maintainers do all what they can to ship programs light and simple. So it goes against at least two Linux principles.

Calling it hate is an exaggeration , people are entitled to their opinion and informing other people by criticizing snap.

Another advantage not mentioned is that snap is a product of canonical (a for profit company talking about an IPO for years), flathub is managed by the gnome foundation (a US registered non profit, which should provide some legal protection).

I especially hate how it ruins the df -h command. Install a dozen snaps and it becomes unreadable

Snaps are proprietary, flatpacks are not, is the long and short of it

When I install this snap am I getting a kernel driver, a native raw binary, or a containerized user application that conforms to a communication interface? Who knows! They’re all mostly undifferentiated in the store.

What about a third party store? Only if you fork the snap daemon and change the hard coded URL. And good luck with that mandatory Canonical contributer agreement you have to sign.

Want to pick when your apps update? Nope. That’s the official stance. They will never support that. But here’s a way to manually block network access to the daemon if you really really need to. But then everything will update at once when you give it access again.

Want a specific version of a snap? See above. Explicitly will never be an option.

“I guess there’s a fee to pay to get access to quality apps.” Incorrect. There is no real vetting process for what’s added to the store, there’s barely even minimal checking that you’re not overwriting someone else’s snap. You do have to sign the Canonical contributor agreement, and setup an identity to submit as, but even if your snap is proven to be malware there a good chance it will stay in the store, or can be immediately re-uploaded.
