I'd like to upgrade from Ubuntu 20.10 to 22.04 but get messages like
An upgrade from 'groovy' to 'impish' is not supported with this tool.
or
Your Ubuntu release is not supported anymore.
following documentation and blogs I have found so far (all require the starting point to be 20.04 or 21.10), eg this otherwise comprehensive tip .
What are the least disruptive options?
