Which will then probably tell you that it conflicts with vulkan-mesa-device-select and asks if you want to replace it. Which might either work or just get you another conflict because vulkan-mesa-device-select is required by some other package.

Yeah, basically. This was my result:

sudo pacman -S vulkan-mesa-implicit-layers
resolving dependencies...
looking for conflicting packages...
:: vulkan-mesa-implicit-layers-1:25.3.5-2 and vulkan-mesa-device-select-1:25.2.6-2 are in conflict. Remove vulkan-mesa-device-select? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: removing vulkan-mesa-device-select breaks dependency 'vulkan-mesa-device-select' required by lib32-vulkan-mesa-device-select
:: removing vulkan-mesa-device-select breaks dependency 'vulkan-mesa-device-select' required by vulkan-intel

Btw… pacman -Qi <package name> usually tells you anything you need to know about a package. In this context mainly why it was installed (as a requirement for which package) and which other packages are required as a dependency.

So maybe you should take one step back first. Check why 'vulkan-mesa-device-select` was installed in the first place.

Okay so I tried that and got:

Seems it’s necessary, so I tried sudo pacman -S vulkan-mesa-device-select and it gave me no trouble, so then I ran sudo pacman -Syu and after just under 10 minutes everything updated! Seems to work again. Thank you very much for the help, I really do appreciate it.

Answering “n” gives me the same error still. Same with if I say no for both questions. In fact, any combination will always result in the same error.

Probably a dumb question but how would I go about installing vulcan-mesa-implicit-layers?

I tried that one too and it gave me the same error.

Thanks for all the info. I tried manually replacing the mirrorlist but I’m still getting the same warnings and errors. I also tried -Syyu but still no dice.

What was this you were saying about keyfile? That doesn’t seem to be something I’m familiar with.
