I guess the installer can't rely on udev for array memebership information and will have to run mdadm --detail or similar itself. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960926 Title: [VROC] Installation on RAID volume fails - ubuntu 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1960926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
