Packages are kept in /var/cache/pacman/pkg.

Delete unused old packages with:

sudo pacman -Sc

Signatures are handled by the pacman-key, initially set up with:

sudo pacman-key --populate archlinux

And refreshed with:

sudo pacman-key --refresh-keys

If you have usigned keys, you can refresh with:

sudo pacman -Sc

or

sudo pacman -Scc

Reset all keys with:

sudo rm -r /etc/pacmand.d/gnupg/ && sudo pacman-key --init

If you're constantly getting 'everything corrupted, nothing upgraded', try running:

sudo pacman -S archlinux-keyring

List all orphaned packages:

sudo pacman -Qtdq

sudo pacman -Rn <package_name> #removing the package

Cleaning Config Files

Arch does not overwrite your changes to configuration files. Instead, it updates them by adding the .pacnew suffix.

So when /etc/pacman.conf receives an update, this will be placed in /etc/pacman.conf.pacnew. These changes must be merge manually.

Install the pacdiff tool to make this easier, from the pacman-contrib package, then simply run sudo pacdiff to sort through the various mergers.

AUR helpers (yay, paru,..)

Installing helper can be done by cloning and building that package from AUR repository, to avoid doing that manually and to automate updating, we use helpers.

Building Yay:

sudo pacman -S --needed git base-devel
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si

Flags are mostly the same as in pacman But running yay without flags will do the update like yay -Syu and with package name it will search packages in aur and pacman repos, and let you choose which to install

yay <search_term>

Building the package can usually take some time, and after the build it will ask for sudo password, if afk installation will fail, to avoid this you can use the flag --sudoloop and enter the sudo password initially and it will loop it untill finishing the installation, to avoid answering all of the installation question --noconfirm can be used

yay -S --noconfirm --sudoloop <package_name>

Pacman and yay text coloring

Getting the colors is done by editing the /etc/pacman.conf and uncommenting the line Color By adding the line ILoveCandy you will unlock soem terminal animations, like one pacman eating the dots while installing some package
