Sometimes, when I log in, a window pops up marked "Web authentication from Google", saying "GNOME Evolution would like to:" followed by a list of things (view and manage mail, view email address etc.
When I enter my login details, the window disappears, then pops up again, and again, and again... Clicking on "Allow" or "Deny" makes no difference, it just keeps coming back. This seems to happen at random occasions on login, and Online Accounts seems to show everything OK.
Why is this happening?
This is a known bug which happens to appear randomly for some users on different Ubuntu editions since a long time ago and here are some examples of already existing bug reports :
In many of the cases it is related to the account-plugin-google and the evolution-data-server packages which may be solved by upgrading to newer packages from the proposed repositories. Example : Temporarily enable trusty-proposed - upgrade relevant packages
Unfortunately there is no guaranty that it solves the problem. As a workaround you have to either logout and back in or reboot the system, which mostly leads to correctly connecting.
You should file a new bug report on Launchpad - just as being suggested lately by Alberto Mardegan to a user who informed about the exactly same issue occuring in Ubuntu 16.10.
