Public bug reported:
While performing an install to a zVM guest using the 20.10 iso from October 1,
the subiquity installer reports:

└────────────────────────────────────────────────────────────────────────┘
This happens just after enabling storage devices, from the installer ssh
session. The inputs leading up to this failure on the SolutionsQA s5lp1-gen02
guest were:
English
dasd-eckd --> 0.0.0200 --> enable
zfcp-host --> 0.0.f201 --> enable
zfcp-host --> 0.0.f301 --> enable
Upon further inspection of the subiquity-debug.log (see attached) the
following traceback is present:
