Comment 7 for bug 1802354

Just for reference, this was actually fixed in disco at 2.0.874-5ubuntu10.
But that never made it into the release pocket before 5ubuntu11 went in.
The relevant changelogs:

open-iscsi (2.0.874-5ubuntu11) disco; urgency=medium

  * debian/tests/test-open-iscsi.py: Fix called process error.
    If no image was available for a release, a NameError exception would be
    raised.

open-iscsi (2.0.874-5ubuntu10) disco; urgency=medium

  * d/iscsi-disk.rules, d/tests: Add a udev rule so that iscsid.service
    will be run when udev disks are attached. (LP: #1802354)
  * debian/tests: improve tgt boot test
     - disable snapd and snap.seeded services to avoid unnecessary
       resource consumption during tests.
     - save artifacts from the test run.
