Why Doesnt My Standard Lock Lock Again

The other day, I was about to update my Arch Linux arrangement. When I endeavour to update the organisation, I encountered with "unable to lock database" fault in Curvation Linux. I could not install or remove any packages.

Here is the command that I entered to update my Curvation Linux organisation:

# pacman -Syu

And, It returned the following error:

:: Synchronizing package databases... error: failed to update core (unable to lock database) fault: failed to update extra (unable to lock database) error: failed to update community (unable to lock database) error: failed to update multilib (unable to lock database) error: failed to synchronize whatsoever databases fault: failed to init transaction (unable to lock database) error: could not lock database: File exists  if you lot're certain a package director is not already  running, you can remove /var/lib/pacman/db.lck

Fix unable to lock database error in Arch linux

Gear up unable to lock database mistake in Curvation linux

The dazzler of Linux distros is sometimes they will the explicitly display the solution along with the error message. As yous can come across in the above output, it says: "..you can remove /var/lib/pacman/db.lck".

So, I simply deleted the aforementioned file with command:

$ sudo rm /var/lib/pacman/db.lck

Voila! It worked. I tin so able to update, install and remove without any problems.

$ pacman -Syu

Sample output:

Check if your user is in sudoers list and so delete the file. In that location is a typo in this line – "/vr/lib/pacman/db.lck". It is var, non vr.

Delight how practice y'all utilize Thunar root to delete the lock files.
Thank you lot.

sk August 8, 2021 - 6:27 pm

Hullo Kunle,

Open Last and run the following command to open up Thunar file manager as root:

pkexec thunar

Browse the file location and delete information technology normally. Delight make sure you have selected the correct file name before deleting information technology.
