Can't update snapweb

[Chris]

Through out the day when it comes time for snap refresh to run I've
noticed that it can't update snapweb. Running manually shows

chris at localhost:~$ sudo snap refresh
error: cannot perform the following tasks:
- Run configure hook of "snapweb" snap if present (/usr/bin/env:
'python': No such file or directory)

I also get this output in my syslog. Mind the extra stuff not
pertaining to the update as there is some here and there.

And what is all this starting here - Feb 18 19:15:07 localhost
/usr/lib/gdm3/gdm-x-session[2315] it shows up each time today that
snapweb was trying to be updated.
