Wifi drivers NOT loading

Support Network
1

i have no wifi… i am on kde plasma… all devices are there with lspci but no drivers… yesterday i tried a live cd usb drive… and every device had drivers and worked perfectly…

I accidentally deleted all files and folders in /var/lib/pacman/local and that way i had no packages installed. After that reinstalled all packages using the script:
pacman -Fl | grep -v ‘/$’ | xargs -d\n -P16 bash -c ‘for arg; do [[ -e “/${arg#* }” ]] && echo “${arg%% *}”; done’ bash | sort -u

Maybe because when i reinstalled all packages they were during a major update and the old files stayed on the filesystem after the update. Are there any GUI programs to select which files to delete that are NOT tracked by pacman anymore?

I see you have the option of connecting using wired ethernet.

When the internal pacman database has been damaged

Sorry - there is there is no such thing

But if you system is up and running AND you can connect using ethernet, you can use the package lists /rootfs-pkgs.txt and /desktopfs-pkgs.txt to build lists you can compare with what you currently know.

The Arch wiki contains several pages on Pacman pacman - ArchWiki and they are very hand in a troubleshooting situation.

The wiki article provides a subsection pacman/Restore local database - ArchWiki

EDIT:

I don’t think the script snippet in the quoted form produced any output.

  • the xargs -d\n should be xargs -d'\n'

When correcting the delimiter I can get a list with two columns

<pkgname> </usr/path/file>
  • the do [[ -e "/${arg#*}" ]] will prepend / to the package name and return true if it exist in root which it don’t

It may entirely be my lousy understanding of bash, so I actually tested the command - it does not provide a package list on my system
