How to Restore AUR Packages to Pamac⚓

Summary⚓

I ran into an issue where the Pamac GUI wasn't displaying all packages from the AUR. I tried the following, but it didn't resolve the issue:

Rebooting the computer
Refreshing the Pamac database

The following is a guide for how to resolve this issue.

Steps to Resolve⚓

Clean the package cache using Paccache⚓

sudo ls /var/cache/pacman/pkg/ | wc -l

du -sh /var/cache/pacman/pkg/

To clean all packages, except the 3 most recent versions, run the following command:

sudo paccache -r

Check again how many packages are left in the cache folder.

sudo ls /var/cache/pacman/pkg/ | wc -l

Now, check the total disk space used by the cache folder.

du -sh /var/cache/pacman/pkg/

Use the following pacman command to remove all uninstalled packages:

sudo pacman -Sc

Next Steps⚓

At this point, the missing packages were still not appearing in the Pamac GUI. The closest I can get to an understanding is that I had outdated mirrors that were being used and were not providing the proper packages. This required the following manual intervention...

Manual Intervention⚓

Check the output of the following command:

ls -al /etc/pacman-*

The output should look like the following:

-rw-r--r-- 1 root root 860 Mar 28 14:10 /etc/pacman-mirrors.conf

Once this is confirmed, run the following:

sudo pacman-mirrors -f5 && sudo pacman -Syyu

This should refresh all the mirrors and perform a complete update and database sync. Once completed, restart Pamac.
