Sketch seems to support what it needs to.
And it can do the text thing.
It ain't purty, or powerful, but text editing it can.
Also, *I* can edit text in Debian Proper with Inkscape and have no problems.
I am Using Inkscape 0.41-2.
One other thing too. You might have better luck with Sodi-Podi (though I know it is different Peter) it might just be ale to edit the text for you after you do the bulk of the work in inkscape.
