When I try to install the graphics driver it shows the following error message. I also tried fixing the broken package but it didn't work.
$ sudo apt-get install nvidia-390 Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: nvidia-390 : Depends: lib32gcc1 but it is not going to be installed Depends: libc6-i386 but it is not going to be installed E: Unable to correct problems, you have held broken packages
if this might help, here is some info about my current system
