I also get this on a fresh install of Ubuntu 19.10 on one of the two machines I use (laptop with wifi is fine, desktop with wired connection is buggy, I used the same USB for install). My internet connection is fine, but some of the websites I want to get on are blocked (e.g. mobile banking, lastpass, etc.) on the affected desktop. I had minor issues on the laptop but changed them by switching the repositories. No such luck on the desktop. The network icon has a question mark over it, but when I open the network dialog, it says Wired Connected -1000Mb/s. I get this error message persistently in my Ubuntu Software:
Unable to download updates from "extensions.gnome.org": failed to download https://extensions.gnome.org//static/extensions.json: Cannot resolve hostname I changed mirrors from local (cz) to general Ubuntu, installed gnome-extensions directly in terminal, ran sudo apt-get update&& sudo apt-get upgrade. All software is reported updated, but the error is persistent as well as the website blocking. Any ideas?
