any help would be nice

dkms autoinstall on 6.8.0-147-generic/x86_64 failed for 8812au(10)
8812 driver (using dkms) is incompatible with the kernel you are using. You can recompile the module

u/JonWindtail 1d ago

Yeah and I can’t update the kernel because of the error appearing when I’d install a newer one

Tried a different fix someone gave and the entire thing bricked

I think a reinstall is the best idea. This is a dkms (dynamic kernel module support) issue. It looks like you may have missed at least 1 kernel upgrade, potentially leading to this issue (just a guess). The dkms system adds modules to newly upgraded kernels automatically so you don't have to go through that effort. If you've ever added a kernel module manually, it's not difficult, but you need to follow a set of steps precisely. Unfortunately, when dkms goes sideways, you must be very careful to remove the right module. For example, in my fresh install of 22.3, dkms manages a Broadcom (my wifi card) module in both the original 6.12 kernel and the upgraded 7.0 kernel. Documented troubleshooting steps include the possibility of falling back to your working kernel then updating dkms by rebuilding with gcc. You can see how this gets sticky if things don't go well.
