Hello! I've found it out, how you can solve/work around the problem:
Nextcloud needs MariaDB. It won't work (so it seems) with MySQL. So mariadb- server needs to be installed. This replaces MySQL (mysql-server-core-5.7 and mysql-client-core-5.7) with MariaDB. The problem is that after that, Akonadi won't start any longer. "aconadictl start" outputs a lot of messages. The problem can be repaired by doing this, after the installation of MariaDB: akonadictl stop rm -r ~/.local/share/akonadi akonadictl start Bye, Volker
