During the Upgrade of my NextCloudPi instance to Nextcloud version 20.0.3 the update panel suddenly blanked out with an error displaying on the top left. When I refreshed the page and tried to press update again it threw me the error “Nextcloud backup directory found. Interrupted installation?”. When I visited my nextcloud instance a button appeared to migrate the database to Nextcloud 20.0.3. When I did that it got into a loophole that stopped at some point out of nowhere. After that almost all my apps where uninstalled as it seems like the nextcloud folder is corrupt or something. Somewhat later I tried to update via the console again then it told me “Malformed version”.
Somewhat earlier I also saw a folder named nextcloud_old under /var/www/ which got deleted for some reason.
That is basically the point I am at right now and I have no idea how I could fix this without destroying anything. Any help will be appreciated
Unfortunately, I am not able to find any backup file or folder at all in my /var/www/ folder. I can only find the folders which you can see in the screenshot below.
I also did not have any form of a power outage during the updating process as well so I, unfortunately, do not know what could have caused this.
I saw it when I accessed that folder like 10 or so minutes after the update but I thought the folder doesn’t matter because it had an older date maybe I miss seen that or something. If I do ncp-update-nc now it tells me that I have a malformed version so it seems it did not go through correctly at least.
Yesterday, my update from NC 18 to NC 19 failed due to a blackout.
I reinstalled my backup but when trying to update NC via NextCloudPi I get the same error message as @anon9850292: “Nextcloud backup directory found. Interrupted installation?”.
I finally updated to NC 19 using the NextCloud-interface. When I now try to update to NC 20 via NCP I still get the same error message. Any idea how I can run updates via NCP again?
