Final Update:
After trying to get the python-enchants dependencies to install as per our conversations it all failed miserably.

"@txe I tried but it was not straightforward because was forcing to downgrade packages versions and pin those versions, so I would not advise the average user to do that. I would rather invite to use the Gtkmm3 version with extra precaution if neither snap nor flatpak satisfy their needs"
So I think for the moment Cherrytree remains broken. I will close this as solved even thought it is not , as it appears the developers are at the end of the road with this.

"@Mizscottie , ubuntu 20 removed all packages related to python2 and which cherrytree uses, thus snap is only an option there, I asked a snap developer to fix issues with snap your mention, will see if it's possible.
@giuspen , I didn't suggest c++ version, because image paste is not working there yet
"
end.

"the snap configuration was fixed. If ubuntu updated cherrytree snap, then the bugfix (to copy an image from a browser) is there."
I updated and yes indeed this error has no been fixed.
Cheers
