Hello Marc,
thank you for your answer
the nextcloud update was not started by me, it just appears when I try to open the nextcloud login page
I usually update nethserver at the command line by running:
yum --disablerepo=epel,centos-sclo\* update (found here)
# grep \'db /usr/share/nextcloud/config/config.php |grep -v dbpass
'dbtype' => 'sqlite3',
# rpm -q nethserver-nextcloud
nethserver-nextcloud-1.22.0-1.ns7.noarch
I should mention, that I messed up the nextcloud Installation in June 2021 so maybe something is not as it should be. But after that time nextcloud seemed to be running without problems.
