[Bug 1770173] Re: 18.04 install stuck on grub install

[Phillip Susi]

So it looks like it is getting stuck running this command:

31197 root     26996 S    dmsetup create -r osprober-linux-sdb1

It also looks like in the cases where it does not hang, there is a
message about not recognizing what filesystem is in /dev/sdb1 and it
can't be mounted, but in the one where it hangs, it seems like it does
recognize it.  I wonder if zfs isn't present in the installer and so it
can't recognize and mount it, but it is installed in the target system,
and it is somehow conflicting and causing the hang?
