I’m enough of a Linux lay user that I’m not even sure if I’m using the right terminology in the question (feel free to tweak it if needed!). Here’s what I mean:

I’m running Pop!_OS currently, and I have at least one app installed via each of the following methods:

• Deb app from the distro repositories
• Deb deb downloaded from program website
• Flatpak app downloaded from Flathub
• AppImage app downloaded from program website
• Snap app downloaded from the Snap store

As someone who doesn’t really know or necessarily even care to know what’s going on under the hood, these all pretty much work identically for me (with the exception of AppImage which doesn’t integrate into my regular programs menu, and the standalone Deb, which requires manual updating). In fact, for most of the programs on my computer I couldn’t tell you which one they’re sourced from. They all just run like they should.

I’ve looked up differences between all of the options and usually end up finding conversations that go well above my head and get deep into technical details. My question here is basically aimed at cutting through a lot of that depth: what is the important, need-to-know information about these different methods of installing apps? Is there anything I should be aware of if all I’m really going to be doing is running them as a standard, non-power user? Also, if an app is available via multiple methods — is there one that is preferred/better/safer/superior/etc.?

Please post your efforts below, with an introduction and/or questions for your readers.
Here are the guidelines, again.

What have you been doing lately for your own fitness? Try out any new programs or exercises? Have any questions for others about your training? Want to vent about poor behavior in the gym? Started a new diet or have a new recipe you want to share? Anything else health and wellness related?

Clicking a tag provides the search results for that tag in the local group. Since some topics appear across groups, I think it'd be useful to view site-wide results as well, optionally. Does that already exist?

What have you been watching and reading this week? You don't need to give us a whole essay if you don't want to, but please write something! Feel free to talk about something you saw that was cool, something that was bad, ask for recommendations, or anything else you can think of.

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL, or any other database you use!

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?
