Thanks for your report. It's very likely due to the nouveau driver crashing. Could you try to boot in safe graphics mode?
To do that, press any key on boot to display the boot menu and select "try ubuntu (safe graphics mode)" If the live session boots, then try an installation and select "Install third party drivers" in the installer. ** Changed in: ubiquity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853986 Title: installer crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1853986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
