Ubuntu delivers Chromium through snap only. Via apt you get only a base package that knocks snap to install Chromium. If snap is not there it claims that snap is not reachable which I was hoping was more clear that snap is not even installed. Well, I guess Ubuntu did not think about a Ubuntu system that could be delivered without it.
Anyway even though the current implementation works it is not very clean. Also discussed here: https://armbian.atlassian.net/projects/AR/issues/AR-278?filter=allissues
