20.04: Optimized SVG save fails due to no python-scour package

[Set Hallstrom]

Saving an SVG to optimized SVG fails. No other feedback available than a prompt message stating:
"File /home/set/setto-logo-dark.svg could not be saved."

Installed scour because i remember that solved it from a previous similar issue, but it didn't resolve this time.

Starting Inkscape from the terminal didn't give me more information.

when using the Inkscape ppa (ppa:inkscape.dev/stable) and upgrading to Inkscape 1.0 (1.0+r72) Pango version: 1.44.7, the bug disappears.

Thanks for checking with the PPA. Indeed way too many things changed between version 0.92.5 and 1.0! :)

Could you perhaps verify whether the version 1.0-5 as currently available in Ubuntu groovy is affected by this bug?

Either way I'm afraid I'm not really available to track down whatever might be causing this with 0.92, so it's unlikely to be fixed in focal :(

There are a couple of problems here, for 20.04 LTS.

1) inkscape package declares a Recommends: for python-scour which does not exist in 20.04 - only python3-scour.

2) /usr/share/inkscape/extensions/scour.inkscape.py depends on python2: #! /usr/bin/python2
