The problem could be solved. The steps described in various tutorials (remove all existing nvidia- packages, install headers etc.) didn't help even reinstalling.
I realized that copying my system to a new disk (ssd :-) ) was uncomplete. After fixing that everything worked again. I don't now what was missing maybe a an apt-get install build-essential would have also helped. There are scattered reports of people with the same problem with various debian and ubuntu versions that might have the same reason. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-304 in Ubuntu. https://bugs.launchpad.net/bugs/1249794 Title: nvidia fails to install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+bug/1249794/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
