I use Ubuntu Mate 20.04. When I use websites like maps.google.com, they won't get my location. It seems Ubuntu Mate has no location service enabled out of the box. On regular Gnome Ubuntu, it seems to be a part of their menu settings, but in Mate, I don't see any such options. I have searched the web a lot, but didn't find any info. It seems no one has ever asked this before. Which makes me wonder if the question is really that unusual.
Oh , and I'm connected via LAN. Maybe it matters, but I don't know. No Wi-Fi, just LAN.
