pacman -Syy refreshes all db for all repositories

Is there a way to have pacman only refresh a single repository db?

Ie pacman -Syy custom only refreshes custom withou refreshing core extra etc Hello,

This question may be simplified to whether pacman can do -Sy on a single repository. Which then is equal to asking, if it has an option to let the user to desynchronize databases. The answer is: no. The pacutils package has `pacsync` command, which lets you work on single repositories. But be aware, that updating a single repository will make databases desynchronized. Unless you instantly fix this and update all the others too, you’re going to end with a partial update. Cheers
