Hi, I use one application from the AUR and need the packages “git” and “base-devel” to build it.

When I try and install it as per below, it shows that everything on the mirror is outdated:

sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman -Sy git base-devel

The output of the last command looks like this:

:: Synchronizing package databases...
 jupiter-rel is up to date
 holo-rel is up to date
 core-rel is up to date
 extra-rel is up to date
 community-rel is up to date
 multilib-rel is up to date

Any suggestions are appreciate. I’m assuming that letting this go through would be a mistake.
