    It's probably a temporary connectivity issue with extensions.gnome.org. – pomsky May 6 '18 at 16:21
  • I'm having this issue on Ubuntu 18.10. This is my personal laptop so no proxy involved. – yahavi Nov 2 '18 at 19:03
  • @yahavi Does the problem still there? You might like to ask a new question. – Kulfy Dec 10 '18 at 20:27

    This only seems to happen on first start up when there is no internet connection. – holmberd Jul 12 '19 at 18:07

I was having same problem, no Internet issue was there. I did following -

Installed gnome-shell-extensions again

sudo add-apt-repository ppa:gnome-shell-extensions/ppa
sudo apt-get update
sudo apt-get install gnome-shell-extensions

I reinstalled gnome shell extension in firefox, and after some time, it started working. After that Ubuntu Software Manager showed no such error.
