On Friday I finally learned how to f*** up my laptop. Just unplug it accidentally during running a system update with “pacman -Su”.

Result: kernel panic on reboot, no help until I found a USB stick containing a archlinux image.

After booting and fixing the kernel image I encountered multiple strange errors from libraries which weren’t been touched during that failed update run.

So after searching and deeper searching, with no evidence of the damaged packages I finally decided to just reinstall the whole system.

First I reinstalled all packages installed by dependencies and then all explicitly installed packages.

#deps:
pacman -S --asdeps $(pacman -Qnqd)
#explicit packages:
pacman -S $(pacman -Qnqe) --force

That ‘force’ was required due to some nasty errors about already existing files, which I did not care about.
