Ubuntu – Installing nvidia drivers on 18.04

18.04driversnvidia

all. I'm trying to fix my system so I can install the nvidia drivers but it seems to get stuck for some reason. I have tried manually removing the downloaded files from 

/var/cache/apt/archives/libnvidia-gl-390_390.48-0ubuntu3_i386.deb
/var/cache/apt/archives/libnvidia-gl-390_390.48-0ubuntu3_amd64.deb

… in order to let them download again but to no avail. Have anyone tried installing those drivers on 18.04 lately?

Best Answer

Found this command on ubuntu forums, worked very well with me:

Run:

LC_MESSAGES=C dpkg-divert --list '*nvidia-340*' | sed -nre 's/^diversion of (.*) to .*/\1/p' | xargs -rd'\n' -n1 -- sudo dpkg-divert --remove
sudo apt --fix-broken install

The first command will remove all the diverted packages from nvidia-340. If you have other nvidia version "diverting" change it; read the error code to know which version is diverting.
