wip/aur: Fix linting issues

The wip/aur branch was not checked for linting issues. Some of them were fixed,
but, particularly the git commands for setting the AUR repo, were skipped, because
the git module does not necessarily cover all the needs. Might be worth taking a look
about it on the future.
