Comment 2 for bug 1786724

Seems the snap packages did not specify Scour as a dependency, should be fixed in
  https://gitlab.com/inkscape/inkscape/commit/26d08e9c5b607e366c69f368682dcc5e17cae835
and
  https://gitlab.com/inkscape/inkscape/commit/f709311ff1b861fe9ccfd79cc21e233075ee94e2

However I'm not using the Snap package (or Linux for that matter), so somebody else will need to confirm wether it works as expected now.
