i have a radeon r7 APU and 20.04 ubuntu and im trying to install the drivers. i downloaded 4 fglrx files (fglrx-core, fglrx, fglrx-dev, fglrx-amdcccle) and when i try to install the fglrx-core i get the error:

Error! Bad return status for module build on kernel: 5.15.0-57-generic (x86_64) Consult /var/lib/dkms/fglrx-core/15.302/build/make.log for more information. dpkg: error processing package fglrx-core (--install): installed fglrx-core package post-installation script subprocess returned error exit status 10

and the other files are all dependante on this one.

i tried purging them and installing them again but that didnt worked.

fglrx drivers are obsolete and can't be installed to modern Ubuntu releases for many years.
