Description
I was working with package manager Octopi, then stops in the middle of installation transaction, want to open window of Pamac app, clicked it's system tray icon and PC freezes at once. Can't switch to tty2, tty3 terminals. No any response from mouse, keyboard. Then hard reset PC.
After PC loads I can't sync packages DBs: Octopi said something close to "can't enter fakeroot environment" and exit sync action with error:
That error was fixed with sudo pacman -S base-devel
. So PC hang leads to package/OS files lost some information.
After that I did global fix sudo pacman -Qqn | sudo pacman -S -
.
Looks like OS still working, but I switched to 5.8 kernel family.
How often does the steps listed above trigger the issue
That bug also was previously for several times on the same kernel version but under different circumstances: working with widget settings window and working with Gwenview app setting window.
So frequency depends how actively PC used as actions by changing some settings. With me was 1-2 time a day. Saw the bug about 3-4 times.
