I installed the amdgpu installer (which worked).
I tried different commands to install the driver itself, but this is what is happening:
amdgpu-install -y --usecase=graphics
Package linux-modules-extra-6.0.8-060008-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'linux-modules-extra-6.0.8-060008-generic' has no installation candidate
Could it be, that Kernel 6 is not supported yet? Any workaround?
