It seems that during the roundcube update there was a problem with the database.
If in the logs /var/www/roundcube/logs/carddav.warn you see messages like : BACKEND: (update_addressbook) [1054] Unknown column 'authentication_scheme' in 'field list' you can refer to the page https://github.com/blind-coder/rcmcarddav/issues/156
The idea is to drop all the tables named carddav_* from the roundcube database then logout and login into rouncube.
On my side I lost some group assignement but all my contacts are there.
Log into mysql and drop the tables in this order (there are foreign keys)
$ mysql -u root -p
mysql> use roundcube;
mysql> drop table carddav_xsubtypes;
mysql> drop table carddav_migrations;
mysql> drop table carddav_group_user;
mysql> drop table carddav_groups;
mysql> drop table carddav_contacts;
mysql> drop table carddav_addressbooks;
Now you can log out the log in. The roundcound will be a little bit slow like everyday because of the database upgrade.
This operation also solved the error 500 and white page in roundcube
Hope this work for you and do not forget to make backup before !!! # --------------------------------------------- 8< ------------------------------------------------------------
Merci pour l’info. Je viens de le faire et cela a marché. La seule chose que j’ai faites en plus, c’est de restaurer la sauvegarde crée avec mysqldump à la fin de la manipulation, car je ne pouvais plus utiliser roundecube.
