YOUSEF
Use the terminal to enter these commands:
sudo rm /var/lib/pacman/sync/*
Then these:
sudo pacman-key –init
sudo pacman-key --refresh-keys
sudo pacman-key –populate archlinux manjaro biglinux
sudo pacman-mirrors -g
sudo pacman --overwrite \* -Syud
sudo pamac update --force-refresh
If this doesn’t work, the package may have problems.
Thank’s for your time
