Extensions do not appear:
No problem. Regardless, it's been resolved in our Visual Studio Code. I've been now using the open source version instead of the Microsoft version, and we've dropped the MS version from 3rd-Party.
I'm not the author of the Remote SSH extension. FWIW, this was brought up as a VSCode Issue first, before coming here. It seems Microsoft are not interesting in supporting builds other than their own. Any chance of a short phrase in Software Center warning people that the Solus build is likely to not work with an unknown number of extensions?
