Comment 2 for bug 1870111

From the problem description, I understand that this happens for a clean installation of thunderbird (because the email setup window is shown), not an existing profile, right?

I cannot reproduce the problem in a clean and up-to-date 19.10 VM: I am able to successfully set up a gmail account.

Does it matter what email provider you set up? (if you can test with a different one)
Did this work before on previous Ubuntu releases / older versions of thunderbird?
