It's a bug. Let's see more.
$ snap info network-manager
name: network-manager
summary: "Network management based on NeworkManager"
publisher: canonical
description: |
Network management of wired ethernet, WiFi and mobile data connection based on
NetworkManager and ModemManager
channels:
stable: 1.2.2-10 (73) 5MB -
candidate: 1.2.2-10 (73) 5MB -
beta: 1.2.2-10 (73) 5MB -
edge: 1.2.2-10 (112) 5MB -
Let's say you install the "beta":
$ snap install network-manager --channel=beta
network-manager (beta) 1.2.2 from 'canonical' installed
Let's try to switch from 'beta' to 'stable':
$ snap refresh network-manager --channel=stable
snap "network-manager" has no updates available
Because 'stable' and 'beta' are currently identical, the channel switching code refuses to make the switch, and start tracking the new channel.
A nasty workaround in this case would be to switch first to 'edge', then switch to 'stable'. Because these are different, the switching will work.
WHAT SHOULD HAPPEN:
If two channels have identical snaps, then 'snap refresh' should be able to change the tracking and track the new channel.
