I use nextcloud on a webserver (all-inkl.com). I want to update from 14 to 15. First I downloaded version 15 and installed it in a new directory. Then I copied the config file and the /data folder into the new directory. When I now call nextcloud I get an update screenshot that I can update to version 15. If I confirm the button, I get an error message that the update failed (Major Update is not supported). I don’t understand the problem!
Did you first update to the latest 14.x version?
What exactly does „installed it“ mean? Did you just copy the files in a new directory, or did you install Nextcloud 15 so that you did login to the new version before copying config.php and the data-folder?
Which version is mentioned in your config.php from your old installation?
Sorry, I’m currently using version 13 (not 14). So I took the following steps.
- download version 15
- unpacked and uploaded to server in new directory
- config file and data directory copied from old directory to new directory
- renamed old directory
- new directory renamed
- nextcloud called
Now the Updater screen appears. I click ok.
- i get an error message, update not possible
