Clean install of Buster on a laptop; mostly working. Since the install, when I get a system message that software updates are available, the updates fail every time. This is in the Software app, which I believe is part of gnome. I get the update notification, but then the following message:
Unable to download updates from "extensions.gnome.org":
failed to download https://extensions.gnome.org//static/extensions.json:
Cannot resolve hostname
The weird thing is, if I ping extensions.gnome.org I get a response from oscp-router02.gnome.org, so obviously some form of name resolution is taking place.
If I run dig on extensions.gnome.org, the returned status is NXDOMAIN.
I ran apt-get update, and did not get any errors.
What am I missing?
