=== Pacman cheatsheet ===
source: [[ https://devhints.io/pacman ]]
== Common commands ==
<code bash>
  pacman -Syu <pkg>     # Install (and update package list)
  pacman -S <pkg>       # Install only
  pacman -Rsc <pkg>     # Uninstall
  pacman -Ss <keywords> # Search
  pacman -Syu           # Upgrade everything
</code>

Install from file:

<code bash>
  pacman -U <package.zst>
</code>

Force overwrite files:

<code bash>
  pacman -S <pkg> --overwrite <pattern>
  pacman -S <pkg> --overwrite \*
</code>

== Query ==
<code bash>
  pacman -Qe            # List explictly-installed packages
  pacman -Ql <pkg>      # What files does this package have?
  pacman -Qii <pkg>     # List information on package
  pacman -Qo <file>     # Who owns this file?
  pacman -Qs <query>    # Search installed packages for keywords
</code>

== Orphans ==
<code bash>
  pacman -Qdt                  # List unneeded packages
  pacman -Rns $(pacman -Qdtq)  # Uninstall unneeded packages
</code>
Avoid orphans by using ''pacman -Rsc'' to remove packages, which will remove unneeded dependencies.

== Other ==
<code bash>
  pactree <pkg>      # What does pkg depend on?
  pactree -r <pkg>   # What depends on pkg?
</code>

=== Key problems ===

Things to try:

<code bash>
  pacman-key --refresh-keys
  pacman-key --list-keys
  edit /etc/pacman.d/gnupg/gpg.conf
</code>

Re-initialize keyring:

<code bash>
  rm -r /etc/pacman.d/gnupg
  pacman-key --init
  pacman-key --populate archlinux
  pacman -S archlinux-keyring
</code>
