[Bug 1854839] Re: Fresh Bionic install hangs forever at 66% waiting for os-prober
I may have found a workaround/fix for this. I noticed that
/etc/grub.d/30-os_prober has a GRUB_DISABLE_OS_PROBER variable that will
skip probing for other OSes on the machine, so I added
GRUB_DISABLE_OS_PROBER=true to the kernel options and the installer
proceeded to completion on a machine that was consistently hanging at
66%/osprober. I'm using foreman for the provisioning so my pxegrub2
template looks like this now:
menuentry '<%= template_name %>_uefi' {
linuxefi <%= @kernel %> auto=true netcfg/choose_interface=<%=
@host.primary_interface.identifier %>np0 url=<%= foreman_url('provision')%>
ramdisk_size=10800 root=/dev/rd/0 rw auto hostname=<%= @host.name %>
GRUB_DISABLE_OS_PROBER=true <%= options %>
initrdefi <%= @initrd %>
}
As soon as I added this option, the install completed. Have only tested
it on this single box, will update again if this doesn't fix it on
future machines.

[Bug 1854839] [NEW] Fresh Bionic install hangs forever at 66% waiting for os-prober
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. ** Affects: debian-installer (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854839 Title: Fresh Bionic install hangs forever at 66% waiting for os-prober To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1854839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

*** This bug is a duplicate of bug 1663645 *** https://bugs.launchpad.net/bugs/1663645 Affecting Dell DSS1500, 100% of the time. SATA drive. Workaround (found elsewhere) is to ctrl-alt-f2 during the hang and "ps | grep dm" and kill the pid running "dmsetup create -r osprober-linux-sda1".

Same as above. The problem appears to be due to an error in the postinstall script, which references "udevd" instead of "systemd-udevd".
