[2.4] python3-maas-client doesn't depend on macaroonbakery

[Florian Guitton]

Good day to you all !

After proceeding successfully to an OS upgrade from 16.04.4 LTS to 18.04 LST the maas CLI refuses to work, pointing to a missing python module:

[Alberto Donato (ack)]

There's a missing dependency on python3-macaroonbakery in python3-maas-client.

A workaround until the fix lands is to install python3-macaroonbakery manually

[Alberto Donato (ack)]

The bug title mentions "snap refresh" but it seems you're using deb packages (at least, the error comes from the deb-packaged CLI).
Could you please confirm you're not using the snap?

[Florian Guitton (f-guitton)]

You are correct. I realized later that it wasn't the snap package and meant to change the title but my spotty connection dropped. I must apologize, thank you for picking it up.
