Yes. Now if you use apt to install Firefox or Thunderbird, it will reinstall snap and install the snap versions of those programs.
If you blacklist snap, it’ll throw an error when you try to install Firefox or Thunderbird cause it can’t resolve their “dependencies”.
You’ll have to install those programs from outside of Ubuntu’s repositories, and the list of affected programs is growing.
Ubuntu’s stated goal is to eventually use snap for all userland apps.

You mean old Ubuntu?

My bank requires a second factor for everything done over the web instance. That second factor is either an app or a hardware token generator you have to buy seperately.

Transaction number. It’s a second factor for authentication of basically everything you want to do while banking online.
Most people use a phone app for it (which doesn’t reliably work on degoogled and rooted phones), but you also have the choice of buying a dedicated TAN generator device, so people without smartphones can use online banking.

Things I need from the Play Store are:

• Banking App
• Banking TAN App
  I downloaded them using the Aurora store and although they complain about missing play services on every startup, they work without them.

Things I don’t need, but use (installed in the same way and run without play services):

• App from my country’s train service
• App from my carsharing service
• Netflix
• Spotify
  I could run those in a browser, but I don’t see what the big difference would be. They run without play services.

So luckily, in Germany, you can live without Google. Nothing actually requires it.

My friends call me “Please fix my printer”.

Framework’s choice for display isn’t Linux compatible.

They really should have set the option Make_Discord_Blurry_On_Framework_Laptops to "false" in the Linux kernel.

Endeavor and Arch both default to a Wayland session currently.
(Tested yesterday)

Every once in a while I try out KDE cause I really don’t like the Gnome way of doing things on a workstation.
And every time so far I was sorely disappointed by how buggy it is all around.
At least default Gnome just works.

Can Firefox install websites as web apps?

Every Windows version was shit when it came out, then became good through updates by the time the next version came out.
Except for Windows ME and 8, which were just shit.

Sometimes I long back for the times when I just used my computer to do things, instead of forming an opinion about the compression rate of my cursor’s image data.

Is EndeavourOS stable enough for everyday use

Yes, as long as you maintain it.

would restoring home with BackInTime just work

Nothing in EndeavourOS really “just works”. You have to install and configure the stuff you need.

Debian by default ships with 100% FLOSS.

Not anymore. The default installation doesn’t use the Linux-libre kernel and enables non-free firmware.

Android is Linux, too.

It will reach Slackware about 6 months before the heat death of the universe.

You don’t know what your ISP-provided router does exactly. It may let some traffic through from the outside. It may get an over-the-air firmware update or config change at any time from your ISP. It definitely has well-known, unfixed vulnerabilities.

Also, if you rely on NAT, you have to have 100% trust in all devices that are inside your network.

When that happens, I’m happy. Cause there is no error when the task is done right.
I mail them a quick step-by-step manual with what they just did while I watched.
When the error happens the next time I can tell them to RTFM and get back to me if that doesn’t solve the issue.

Thank you for your valuable contribution.

What did it say?

I’ve had users who legitimately did not understand this question.
“What do you mean, what did it say? I clicked on it but it still didn’t work.”

Then you set up an appointment to remote in, ask them to show you what they tried to do, and when the error message appears, they instantly close it and say “See, it still doesn’t work. What do we even pay you for?”
I’ve had remote sessions where this was repeated multiple times, even after telling them specifically not to close the message. It’s an instinctive reflex.
