I had this problem in Mint, and what I found is that if there is a conflicting Google account signed in on Chrome (in my case) it won't work. I had to log out of that other account, and it began working. So it seems (as mentioned somewhat, above) that it is very dependent on what you are signed in on with your browser.
I run a 2nd Google account out of Chrome for work, and use Brave for my main Google browser -- so each browser uses a different account. Had to switch both to the same that I wanted Gnome to use (although I suspect the only one it really needed to be signed in the same with was Chrome). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1712279 Title: Can't add google account, shows "credentials have expired" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1712279/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
