Public bug reported: Installing Ubuntu 18.04 cleanly on boxes that have 14.04, the installer hangs at the end during "update grub" at 66%, forever, until I switch to another console and kill the pid of "dmsetup". Issue is described in more detail here: https://jrs-s.net/2019/05/31/ubuntu-18-04-hung-at- update-grub-66/ . I am doing a netboot preseed install using the 4.15.0-62 kernel and initrd from October 2019. When provisioning ~15 boxes at a time, 90% - 100% of them are afflicted by this. If I power cycle them and PXE them into the installer again when hung they usually run to completion.
