I have encountered this issue trying a fresh install of Kubuntu 20.04.1. The entire reason that I tried a fresh install is that trying to upgrade my existing system from Ubuntu Mate 18.04 to 20.04 resulted in the upgrade finishing with errors and leaving my system in an unusable state (fortunately, I have a full backup, so rolling back a failed upgrade is painless, other than the time consumed). I don't know if the root cause of both issues is the same or not.
My graphics card is an NVidia GeForce GTX 750 Ti. /var/log/syslog from the failed ground-up installation is attached (I attempted installing twice in the live session with failures both times). I will attempt to find time to retry the upgrade and attach the syslog from that so we can see if the root cause is the same (I have already rolled the filesystem back from backup for the previous attempts, so I don't have a syslog for them). The end result is that I have no upgrade path from 18.04 to 20.04. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1871268 Title: Installation fails when "Install Third-Party Drivers" is selected Status in GLibC: New Status in Ubuntu CD Images: Fix Released Status in apt package in Ubuntu: Confirmed Status in glibc package in Ubuntu: Invalid Status in apt source package in Bionic: Confirmed Status in glibc source package in Bionic: Fix Released Status in apt source package in Focal: Confirmed Status in glibc source package in Focal: Invalid Bug description: Please use the latest daily installer images if you would like to enable third-party drivers during installation: http://www.cdimage.ubuntu.com/focal/daily-live/current/ [Original Bug Text] Test Case 1.
