Yes i tryed to fix up but i get after on upgrade “Wrong checksum” did you want to install it anyway? i select yes, not i can not use zypper up i get segment failed. So what to do? Firefox is issue back again cashes on boot i get some frizes when i try to upgrade firefox\thunderbird so have someone idea how to solve this? I have many computer but did not understand why opensuse is the most buggy distribution also mageia. Only issue with fedora is when you upgrade and install alot but opensuse have more issue.
Mageia 8 and openSUSE Leap are absolutely robust and stable distributions which you can only break by doing absolute nonsense.
Whithout showing the actual terminal output and your repolist, nobody can help you.
zypper lr -d
Segmentation fault (core dumped)
you are doing something strange.
Apparently you are mixing repositories of different OS versions. This causes bugs and instability
I would recommend a clean reinstall with only the correct repositories.
If you use nvidia be aware kernel 6.3.9 has issues with nivdia.
you can easily reinstall many applications just by naming them together in the terminal, faster than via Yast
sudo zypper install firefox gimp inkscape
