[Evolution] Bug#795287: evolution-data-server: Cannot connect to gmail account any longer

[Svante Signell]

Package: evolution-data-server
Version: 3.16.3-1.1
Severity: serious
Tags: sid stretch

Hi,

With the latest debian packages, 3.16.3-1.1 evo cannot any longer
connect to Contacts and the gmail account:

Failed to connect to 'Contacts'
Cannot find a corresponding account in the org.gnome.OnlineAccounts
service from which to obtain a password for 'a.b at gmail.com'

Failed to connect account 'a.b at gmail.com'
The reported error was "Source 'a.b at gmail.com' doesn't support prompt
for credentials.

This problem has been found in archlinux already:
https://bugs.archlinux.org/task/45394 and reported to work OK with
3.16.4, so please package that version or the latest version 3.16.5 in
sid.

Communicating on the evolution ML gave the following answer (quoting
Milan Crha):

> Aah, it references even the fix (kind of), and reports 3.16.4 has it
> fixed. They are right, the fix doesn't correct already broken account,
> it "only" avoids breakage of newly created accounts, thus the recreate

> Just go to Edit->Preferences->Mail Accounts and delete the GMail
> account there. Then create it again, but do not let it create the
> Contacts. The Contacts require OAuth2 authentication, which evolution
> currently supports only through GOA.

> I do not think the roundtrip of adding the new account will be of any

and in a later mail:
