@Simon, But I want to add that in BIOS mode (alias CSM in this Toshiba laptop) it is possible to install Lubuntu Cosmic from the cosmic-desktop- amd64.iso file dated dated July 11 2018.
This is a great step forward :-) So now we can focus on UEFI mode and in the next step secure boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781015 Title: Calamares fails in UEFI mode after external command in Lubuntu Cosmic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calamares-settings-ubuntu/+bug/1781015/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
