[digiKam-users] Migration from 4.x to 5.x problem

[Chris Green]

As I said elsewhere I have just upgraded my desktop system from
xubuntu 16.04 to xubuntu 18.04.  Digikam is thus upgraded from 4.12 to
5.6.

It now fails to start, when run from the command line I see the
following:-

    chris$ digikam
    digikam.general: AlbumWatch use QFileSystemWatcher
    digikam.general: Database Parameters:
       Type:                     ""
       DB Core Name:             ""
       DB Thumbs Name:           ""
       DB Face Name:             ""
       Connect Options:          ""
       Host Name:                ""
       Host port:                -1
       Internal Server:          false
       Internal Server Path:     "/home/chris/.local/share/digikam/"
       Internal Server Serv Cmd: "mysqld"
       Internal Server Init Cmd: "mysql_install_db"
       Username:                 ""
       Password:                 ""

    QSqlDatabase:  driver not loaded
    QSqlDatabase: available drivers: QSQLITE

I can't find anything like 'qsql' in the ubuntu repository, so what might I be missing, or 
what else do I need to do to fix things?
