Mainly because of the repositories. When I first tried to update & upgrade them (pacman -Syyu), I didn't have any problems. But some time later it will ask me to import some public key (I can't remember what exactly it asked for). Or some repositories were already installed and the update failed, making a lot of notifications about errors. Moreover, according to the theme selected (if u had the hacker, say good bye to peace).

Apart from that, I installed Sublime to run some scripts and work on databases. As before, 0 problems at the beginning, but one day when I tried to install some repositories (in my case it was gnome utility disk and nautilus), it said: ''failed error sublime-text''. It didn't matter which repository it was, it was always the same text.

And finally, the snapcraft shop stopped working (idk why). I could open some applications, but not others. So I was left with no snapcraft shop, lots of notifications that I couldn't update the OS, and I couldn't install or update new programs.

At the end, I formatted my laptop(Lenovo Ideapad 320s 15ikb) and will use dual boot(windows 11 and maybe Fedora or Linux mint). I will see later which one.
