I moved about a month ago and haven’t touched my pc a whole lot from before packing it away and finally getting around to unpacking it.

I’m running CachyOS and finally got around to unburying it, and after trying to run a system update I’m met with this:

sudo pacman -Syu

:: vulkan-mesa-implicit-layers-1:25.3.5-2 and vulkan-mesa-device-select-1:25.2.7-2 are in conflict

I’m not super technologically inclined, not completely illiterate but no expert for sure. Usually I’d update my system regularly but with the move and otherwise being extremely busy lately I’m only getting around to it now. I tried looking it up first but I’m not sure if I just used the wrong search queries or what, but I couldn’t get a good answer anywhere, so I thought I’d try here.

Thanks in advance for any help. I really do appreciate it.

Update: I got it working again! Thanks for everyone who offered help, and especially thanks to Ooops@feddit.org. For anyone who may have the same issue in the future, all I needed to do was update the conflicting packages on their own before doing a full system upgrade and it worked.

    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?

      pacman -S vulcan-mesa-implicit-layers

      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.

      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. If it’s not dependency of something else you can either remove it (or replace it) alongside its lib32 version.

        Yeah, basically. This was my result:

        sudo pacman -S vulkan-mesa-implicit-layers

        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.

        Okay so I tried that and got:

        pacman -Qi vulkan-mesa-device-select

        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.

      remove is -R

      so

      sudo pacman -R vulcan-mesa-implicit-layers

      You can force it to ignore dependencies (be careful doing this as it is bypassing an important safety check in the package manager), for example if you’re trying to remove a package that you’re going to replace with another one then you can ignore the dependency warning when you try to remove it.

      Use -Rdd to remove and ignore dependency checking.
