After update nextcloud to 14.0.6-1 app lost database?

hello,

i updated nextcloud from 14.0.6-0 to 14.0.6-1. After the update ( no failiure shown) i get the basic installation mode from nextcloud. I have to set database, passwords and so on.

where did i get these information, so that i could find the databse in my system?

thanks for the answer
