Php5.0-fpm <> php7.0 Failed to reload php5-fpm.service Using 3.2.2 (The user xx was not found)

After setting up a new Yunohost Server 3.2.2. the installation of 4 other apps brought the failure:
"The user “adendav2 (for ex.) was not found”.

together with this I always found this:
“Failed to reload php5-fpm.service: Unit php5-fpm.service not found.”

I guess the problem is systematic in the change to php7 in yunohost3 ?
any hint?
