Comment 7 for bug 1942930

Hm, maybe I'm holding it wrong (again) but I'm not sure this is fully fixed:
$ apt list netplan.io
netplan.io/now 0.103-0ubuntu5~21.04.2 amd64 [installed,local]
$ $ zcat /usr/share/doc/netplan.io/changelog.Debian.gz |head -n 6
netplan.io (0.103-0ubuntu5~21.04.2) hirsute; urgency=medium

  * Backport patches from impish:
    + Add d/p/0006-netplan-set-make-it-possible-to-unset-a-whole-devtyp.patch:
      Fix unset of a devtype subtree, e.g. "netplan set network.ethernets=null"
      (LP: #1942930)
$ netplan get
network:
  renderer: NetworkManager
  version: 2
 netplan set network=null
Traceback (most recent call last):
  File "/usr/sbin/netplan", line 23, in <module>

    for devtype in network:
TypeError: 'NoneType' object is not iterable

But maybe that is a different bug that needs to be reported differently. Anyway, I can probably work around this one.
