If you're using
lib32-mesa-git), you might occasionally run into the issue where pacman/yay refuses to upgrade them as it complains upgrading accompanying and required
llvm-libs package conflicts with what the currently installed
It's a bit odd. You'd think that shouldn't be a problem as you're upgrading exactly those packages anyway, but that's how it seems to be.
Fortunately you can still encourage an upgrade, and it's as simple as adding the
--nodeps). This flag skips the dependency version checks. With this simple flag added you can proceed with the upgrade as normal.
As it might bring unforeseen issues when using this option in other situations, I would recommend you only use it specifically for
lib32-mesa-git. Whenever I run into this dependency oddity —which, fortunately, does not happen every time— I simply upgrade
lib32-mesa-git first, and then proceed with a full upgrade for whatever may be left.
❯ yay -Sd mesa-git lib32-mesa-git
After this upgrade is down, you can now proceed with your system upgrade as usual.
I hope this helps!
