Public bug reported: I don't know if this is a new problem, I guess I could try installing Ubuntu18 again. On this THinkpad T480 I had a hard time with grub (UEFI related), eventually resorting to a 'dd' from the original disk, when I changed the hard drive. So perhaps it's relted to this. But if not, the situation is pretty simple:
I boot from USB, the installed drive is actual a USB mounted SSD, sdb, and the original U18.04 is on sda. The command "grub-install /dev/sda' works fine when I'm booted in U18. But when installing the U20 from the USB to the SSD, grub-install fails. I think something was already send automatically to the developers, but it then threw me into launchpad. lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: ubiquity 20.04.9 [modified: lib/partman/automatically_partition/question] ProcVersionSignature: Ubuntu 5.4.0-21.25-generic 5.4.27 Uname: Linux 5.4.0-21-generic x86_64 ApportVersion: 2.20.11-0ubuntu21 Architecture: amd64 CasperVersion: 1.442 CurrentDesktop: KDE Date: Sat Apr 11 11:33:13 2020 InstallCmdLine: file=/cdrom/preseed/kubuntu.seed maybe-ubiquity initrd=/casper/initrd quiet splash --- maybe-ubiquity LiveMediaBuild: Kubuntu 20.04 LTS "Focal Fossa" - Beta amd64 (20200401) SourcePackage: grub-installer UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: grub-installer (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal kubuntu ubiquity-20.04.9 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872207 Title: grub could not write to /dev/sda To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1872207/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
