I installed nexcloud and imported the database and the data folder, so far no problem, when I started everything from the browser I received the following message:
Application update required
The following applications will be updated:
Activity (activity)
WebDAV (dav)
Federated file sharing
Files (files)
PDF viewer (files_pdfviewer)
Provisioning API (provisioning_api)
These incompatible applications will be disabled:
diagnostics
files_texteditor (files_texteditor)
gallery (gallery)
market (market)
music (music)
Make sure you have created a backup copy of the database, config folder, and data folder before proceeding.
To avoid timeouts with large installations, you can run the following command from the installation folder:
./occ upgrade
By clicking on update I get:
Exception: Updates between multiple major versions and downgrades are unsupported.
opening the recommended page, I tried to update from the terminal but I receive this: pi@raspberrypi:/var/www/nextcloud $ sudo -u www-data ./occ upgrade
Can you elaborate on what you did? It sounds like you are doing more than an update.
What are you importing your database and data from? And why?
It sounds like you’re trying to migrate from a different (and also older) Server installation. You can’t jump more than a single major version at a time (whether migrating or updating).
