So I'm trying to install the crimson driver on ubuntu. I have done it before without issue. Whatever the reason now I cd into the directory that has the installer and type
sudo ./amd-driver-installer-15.302-x86.x86_64.run
and it tells me
sudo: ./amd-driver-installer-15.302-x86.x86_64.run: command not found
and without sudo it tells me
bash: ./amd-driver-installer-15.302-x86.x86_64.run: Permission denied
and apparently I put the administrator password in wrong twice during install because I can't get it to tell me anything other than Authentication failure.
le sigh.
