Arch Linux update some specific repository

Question

How to update a specific repository database? When I use pacman -Sy it updates all the repositories i.e. core, extra, community.

Is there any option so that I can sync database for some specific repository? I know it can be done by commenting out other repositories in pacman.conf. If there is some specific pacman flag, than temporarily changing the pacman.conf.

Answer 1

As far as I can tell from the pacman man page, it does not seem to be possible no. The best you can do is edit pacman.conf then upate and then revert packman,conf to what you had before.

This is not really such a good idea though, you should always have everything updated properly.
