Thanks a lot for those 2 files, I compared side by side and it called my attention:
https://pastebin.ubuntu.com/p/VJXrJHsqRB/ this difference: + partmap /dev/vda1 | + partmap /dev/sda Error: /dev/vda1: unrecognised disk label < Which Im currently investigating (and why it picked /dev/vda1 instead of /dev/vda like it should). That, likely, triggered the logic to keep select_bootdev as "/dev/mapper": + log 'debug: select_bootdev: arg='"'"'/dev/mapper'"'" | + log 'debug: select_bootdev: arg='"''" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838525 Title: LVM setup fails to install grub on virtio storage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1838525/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
