I just recently became a department manager at a grocery store.

For us, any product close to expiry has three options. Reduce price by half, put product on FlashFood (an app for connecting grocers and shoppers to sell product at steep discounts), or freeze product at or before expiration date and donate to the food bank. Depending on the product, some can also be reused as an ingredient for the meals section. The goal is zero food waste for the whole corporation by 2030. The only exception to that I guess would be damaged product (punctured packaging, bad seal, etc).

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.
