Okay, so you have Arch Linux installed and let’s say you’re wifi isn’t working and you need the package “iwlwifi-3945-ucode-15.32.2.9-2-any.pkg.tar.gz” to fix this but you don’t have a wired connect. What do you do? Blast in your Arch cd, mount it, mount the packages sqfs file and install using pacman.
Mount cdrom:
mkdir /mnt/cdrom/
mount /dev/cdrom /mnt/cdrom/
Mount *-pkgs.sqfs:
mkdir /mnt/pkgs/
mount -o loop core-pkgs.sqfs /mnt/pkgs/
cd /mnt/pkgs/
Install pkg.tar.gz:
pacman -U package-name.pkg.tar.gz
