Installation can not be finished on Yunohost

[Maximilian-tek]

I installed Yunohost yesterday on my Rasperry Bi 3 B. Now when I try to install etherpad mypads on Yunohost I will always get the same error -> LogFile for complete Error List. First some Warnings like: /!\ Packagers! This app is still using the skipped/protected/unprotected_uris/regex settings which are now obsolete and deprecated... Instead, you should use the new helpers 'ynh_permission_{create,urls,update,delete}' and the 'visitors' group to initialize the public/private access. Check out the documentation at the bottom of yunohost.org/groups_and_permissions to learn how to use the new permission mechanism.

Then: ERROR 1146 (42S02) at line 1: Table 'etherpad_mypads.store' doesn't exist

Ensure that all dependencies are up to date... If this is the first time you have run Etherpad please be patient.

RESTART!

And final an Error: etherpad_mypads kann nicht installiert werden: Im Installationsscript ist ein Fehler aufgetreten after that the Programm will deinstall the etherpad.

I tried several Installation options, but always the error that will result in the deinstallation. If it would install (installation without Mypad, I cannot reach the Etherpad and get a Gateway 502 Error with nginx.
