After reading Jason Straight's bug-report, perhaps the missing package is not "libgoocanvas2-perl", but "libgoocanvas" instead. He says:
"The only candidate for libgoocanvas is libgoocanvas2-perl, which is not providing necessary components."

Perhaps if we could include the "libgoocanvas" package from 16.04, in the 18.04 repositories, the editing feature would "just work"?
If that code works, "as is", who cares if it is being actively developed? Put it "as is" into the 18.04 repository. Right?
