I've attempted to re-look at this, see https://discourse.lubuntu.me/t /exploration-of-lp-1864787-sfdisk-force-append-dev-sda/2074/4
but in summary (same sda8 & sda9 partitions, I didn't try any BTRFS, only using ext4, replacing with new ext4 for /) - hirsute installed on d755-5 twice without issue (http://iso.qa.ubuntu.com/qatracker/milestones/419/builds/225461/testcases/1701/results/) - focal installed on d755-5 once successfully without this issue (http://iso.qa.ubuntu.com/qatracker/milestones/408/builds/225460/testcases/1701/results/) - focal installed a second time (different daily ISO) again without issue (http://iso.qa.ubuntu.com/qatracker/milestones/408/builds/225688/testcases/1701/results/) I'll endeavour to repeat the install on occasion Re-reading the original issue, the primary thing I notice missing is I was only used EXT4.. no BTRFS or XFS was used in these tests -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864787 Title: Lubuntu failed install "sfdisk --force --append /dev/sda" To manage notifications about this bug go to: https://bugs.launchpad.net/calamares/+bug/1864787/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
