Not good, but work. Thanks! 👍

Awesome, thank you!

(BTW, you can also use pacman --needed so you don't reinstall anything, and uncomment the Color line in /etc/pacman.conf to get colored output. Just thought to let you know :) )

I FOUND!!! Just comment CheckSpace in /etc/pacman.conf

Fixed mine! thanks

Thank you so much!
