package fglrx (not installed) failed to install/upgrade: il sottoprocesso installato script di post-removal ha restituito lo stato di errore 1

[Ricardo]

I have automatic updates enabled and this morning an automatic update was proposed for fglrx-updates-core, fglrx-updates and fglrx-amdcccle-updates.
After the updates, it was not possible to login into the system. After the login screen, the system worked a little bit and requested the password again (yes, the password was correct :-))
to fix the problem i started in recovery mode, started the network and opened a root session. Using "apt-get remove" I removed fglrx-updates-core, fglrx-updates and fglrx-amdcccle-updates and the system worked properly again.
After login, i opened synaptic and looked around. They were 3 "fglrx-xxxx" packages not configured and I tried to remove them. This action caused the crash.
Regards,
Ricardo
