Just FYI
It is pretty easy to fix. If you don’t want to wait for a successful reanimation you can download the folder “imprint” place it under nextcloud/apps folder and then edit:
apps/imprint/appinfo/info.xml
Change lines
<dependencies>
<owncloud min-version="7" max-version="9" />
<php min-version="5.3"/>
</dependencies>
to:
<dependencies>
<nextcloud min-version="11" max-version="12" />
<php min-version="5.3"/>
</dependencies>
The app can then be enabled on the Web GUI by the admin under “Apps”.
I just tested it and it works.
Can you give me a hint what to write into such an impressum for a Nextcloud server? German is alright for me
