I confirm this problem still active in the latest Release ISO images for 20.04.1-LTS. Obviously a regression consistent with the ~vorlon observation(s) -- didn't happen in 19.04 or 19.10. Involves PluginInstall.py failing to find exact versions of several packages, although I's unable to screen-shot prior to Installer terminating. Even with the ~qd0t workaround, openlp crashes on open, which didn't happen on 18.04.4-LTS.
Attempted clean install on four partitions: /boot (ext2), 4 GiB swap, /home (ext4), / (ext4) emachines/acer EL1210-09 (Acer DA078L) Advance Micro Devices Athlon 64 LE-1620 (P/N AD1620IAA5DH) nVIDIA nForce 780a MCP (C77 64-bit geForce GPU in northbridge) msi GT610-1GD3-LP (nVIDIA GF119 64-bit GPU, 1 GiB DDR3 VRAM) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871268 Title: Installation fails due to useless immediate configuration error when "Install Third-Party Drivers" is selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1871268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
