Public bug reported: Trying to install 18.04.2 on to existing assembled RAID system. Got to the grub installation phase and it then generated an error dialogue window saing it could not install to /dev/sda /dev/sdb (the usual for RAID) but none of the alternatives in the radio button choice actually allowed a continuation.
If it could not do the grub step then the alternatives ought to at least work! $ lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 $ apt-cache policy ubiquity ubiquity: Installed: 18.04.14.12 Candidate: 18.04.14.12 Version table: *** 18.04.14.12 500 500 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 18.04.14 500 500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubiquity 18.04.14.12 ProcVersionSignature: Ubuntu 4.18.0-15.16~18.04.1-generic 4.18.20 Uname: Linux 4.18.0-15-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CasperVersion: 1.394 Date: Wed Jun 12 21:22:17 2019 InstallCmdLine: file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd quiet splash --- LiveMediaBuild: Ubuntu 18.04.2 LTS "Bionic Beaver" - Release amd64 (20190210) SourcePackage: grub-installer UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: grub-installer (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic ubiquity-18.04.14.12 ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832643 Title: Installer crash on RAID system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1832643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
