nextcloud installation


I’m trying to install nextcloud according to


Regardless what I try, install packages, install directly the nextcloud version, I can’t find a way to install the nextcloud data on another than the default path. Whenever I start nextcloud for the first time in the browser (localhost/nextcloud), for a second there is a window with the default path and so on, but it is replaced in a second by a window asking me to create the admin account and warning me I had chosen a sqlite database, which is wrong.

Any ideas?

I gave up and installed rasbian and their nextcloud.
