@galgalesh Might want to update this page for what I hope is an edge case…
On Ubuntu Desktop 18.04, when I installed snapcraft with:
sudo apt install snapcraft
If I run “snapcraft extensions”, I get no extensions supported.
I later tried installing it as a snap… but got the same result.
sudo snap install snapcraft --classic
And there is nothing in this page that details how to install gnome extension if it’s not there.
I noticed it when I was following Java applications and ran Snapcraft in the git clone directory.
