Have you encountered the error from the image above when upgrading your Nextcloud instance?
I did and it is a good thing that the fix is very easy. Basically, you just need to delete the “.step” file(s). Make sure the folder updater-<some-hex-characters> is owned by www-data (Debian) or apache (CentOS). You can locate this updater-<some-hex-characters> directory under your /data.
I am using Turnkey Linux Nextcloud and the based OS is Debian 10.
chown -R www-data:www-data /srv/nextcloud_data/updater-9afd85a661s2d
Once done, go back to the web UI Settings and run the updater again and the error is gone as shown in Figure 1. At this point, click on the Continue update
From here, everything is back to normal. Follow the prompt and the upgrade will be completed.
Cheers!
Perfect and Easy solution. It did work beautfuly. Thanx só muchacho.
