I installed MAAS 2.7.3 with snap (maas 2.7/stable) and it works without any problems.
As expected, the version is old, so I tried to upgrade to 3.2.10.
As a result, the following results were displayed. Is there no MAAS 3.2/Stable?
$ sudo snap refresh --channel=3.2/stable maas
error: snap "maas" is not available on 3.2/stable but is available to install on the
following channels:
3.2/candidate snap refresh --channel=3.2/candidate maas
3.2/beta snap refresh --channel=3.2/beta maas
3.2/edge snap refresh --channel=3.2/edge maas
Please be mindful pre-release channels may include features not completely tested or
implemented. Get more information with 'snap info maas'.
$ sudo snap refresh --channel=3.2 maas

$ sudo snap refresh --channel=3.1/stable maas

P.S. MAAS 2.7.3 is currently running on Ubuntu 20.04.
Oh…
I was able to update as long as I didn’t upgrade all at once.
