Comment 2 for bug 1950656

Inkscape version 1:1.1+202109281949+c3084ef5ed~ubuntu20.04.1 doesn't come from the Ubuntu archive.

We can't provide upgrade paths from packages that come from who knows where.

Besides, looking at that error, I assume that inkscape binary you got already contains the tutorials, so I don't think you should install this package at all

(inkscape-tutorials used to be inside the main inkscape binary package, but was split off to reduce the installed size of a normal installation).
