Recently, I am facing problem to download software from software manager but it is showing error:
Failed to prepare transaction
Target not found: texlive-basic
What should I do?
Try
sudo pacman-mirrors --fasttrack && sudo pacman -Syyu
pamac update --force-refresh
This is fairly similar to the above. But depending on when you last updated, you may need to update via pacman first in order to address an issue with pamac.
