I’ve run this:

sudo apt-get purge inkscape
sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt-get update
sudo apt-get install inkscape

and then

inkscape –version

still gives me

Inkscape 0.92.5 (0.92.5+68)

(even though the software page seems to indicate that 1.0 is aavilable) and when I unpack the inkscape extensions & press apply after selecting ‘Toggle pen between up, down’ according to Section 4.4 of the intro guide, inkscape gives me this:

My distribution is Trisquel (flidas.)

What do I do?
