Hi,
I upgraded to jessie this week. After sudo apt-get dist-upgrade I had to restart my server manually because I couldn’t access my server with ssh (all users seem to have disapeared). After reboot I could do sudo dpkg-reconfigure yunohost-config-slapd yunohost-config-others and since I did it, all is working well.
However since the migration I receive this mail every day:
/etc/cron.daily/spamassassin:
Job for spamassassin.service failed. See ‘systemctl status spamassassin.service’ and ‘journalctl -xn’ for details.
invoke-rc.d: initscript spamassassin, action “reload” failed.
Then I had to restart spamassassin with sudo service spamassassin restart.
Edit: This problem can be solved with the method described here
