Public bug reported:
The symptom is similar to 1611074 but the cause is different. In this
case it seems there is an error accessing /dev/sdb1 when lsblk is run,
possibly because sgdisk isn't done creating the partition. The specific
error message is "/dev/sdb1: not a block device." A simple wait and
retry here may resolve the issue.
