yesterday I updated the kernel version to
4.2.0-42-generic through update manager. This unlucky event caused nvidia drivers to stop working, resulting in the famous login loop issue, after rebooting.
Today I found the same problem, for the very same reason, was reported in this launchpad bug few days ago.
Trying to fix that I messed things up a little bit, so I backed up my data and reinstalled ubuntu 14 without internet connection, which has kernel
4.2.0-27-generic. is there a way to manually upgrade to kernel
4.2.0-41-generic? maybe through apt?
