The certificate of example.com refreshed just a few hours ago, if verification fails on your system check your clock (do time and timezone match?)

Of course it won’t do anything, you need to update (refresh the index) before you upgrade (download and install updates), silly you

Latvia is partly involved, yes, but it’s also part Russian and recently moved to Singapore. You may find the history section on Wikipedia interesting; it also lists the russian part-ownership as reason for many users leaving OnlyOffice (and I’ve seen quite a few posts on that at the time).

As for the open-source part, I stand corrected, thank you

From what I can tell, OnlyOffice has the best compatibility and the nicest UI (similar to MS office), same as with the regular applications. NextCloud Office is based on LibreOffice (officially Collabora, which is their name for the web product), so again same as the regular applications you’ll have some compatibility issues. That said, if you don’t need compatibility with existing documents or only documents made with LibreOffice, either is fine.

One concern many have is that OnlyOffice is closed source (edit: my bad, it’s been open-source for a long time) and russian based (edit: partially russian, see Wikipedia), while LibreOffice is open source.

This would likely only hurt the end user. Many use chromium-based browsers, so you’re just driving those away.

You can detect Firefox, so you can do a superficial block in JS, but lemmy is such a simple site that you’d find it hard to find areas where there’s actual differences between the browsers, those usually only come from complex pages like video calling

Not quite correct. For html, that is to signal standard compliance, you can leave it away and the browser will still handle it. For the bash one, all (most) shell scripts use .sh, so you need to give a shebang to tell the loader which executable (sh, bash, zsh, csh, …) to use

Also on Linux xdg does take file extensions into account, just executables do not

You can start steam just fine without the packages. In fact, if you install without them, it’ll ask you to install them every time, but you can skip that and it’ll work, just 32bit games won’t launch

Edit: Looks like I’m partially wrong, as pointed out by a commenter below, steam currently only launches the 32-bit version of the client, despite support for a 5l64-bit client

555 is still in beta, so I wouldn’t be surprised if something doesn’t work. That said, I haven’t experienced what you have (on GTX 1070 TI), though using 555 causes lots of kernel errors for me. Checking dmeg might reveal something in your case as well.
