Comment 120 for bug 1029289

Franko, thanks for the info; we need to find out why this doesn't work for you, so I'm going to ask you some more questions:
1) Did you restart the session after the upgrade (evolution has some long-running processes in the background -- it may be that while you have the new packages installed, the old processes are still active)?
2) Please check the version with "apt-cache policy <package-name>"; it shows all the available versions, and the one currently installed as a "*" next to it; please use that on "evolution-data-server", as well as those packages listed by Mathew.

Then, if the problem still persists, could you please disable the calendar service from the google account and type this in a terminal:
    export G_MESSAGES_DEBUG=all
    export CALDAV_DEBUG=all
    export GOOGLE_BACKEND_DEBUG=1
    killall evolution-calendar-factory
    /usr/lib/evolution/evolution-calendar-factory > evo.log

Then, quickly start evolution and enable the calendar service from Online Accounts. Wait a few seconds, and then you can close evolution and type Ctrl+C in the terminal. There will now be an "evo.log" file, which should contain important information which we need in order to debug the issue. Please be aware that this might contain some sensitive information: in particular, if you see some lines like "Authorization: Bearer ya19.gwCZsafharuifnaeifnasfGDSds", replace the last part with some random characters.

After you've done that, please attach the evo.log file to this bug report.
