Public bug reported: the bug is due to a php5.6 version incompatible with the php7.4 used in the latest phpmyadmin. Have to keep php5.6. It would therefore be a good thing that php dependant installations check php version, alerts on it but also proposes previous version of whatever has to be installed (here phpmyadmin - i installed the previous version which solves my problem).
