Looking to upgrade my nextcloudPi. I have a good trouble free system running 12.0.3 on nextcloudpi build v0.41.6
In the admin page I am offered the update to NC 12.0.4, when I attempt to do the update I fall at the first fence in that I get an error as shown in the attached.
What am I doing wrong and what is the best upgrade process?
If I remember that past upgrade I did I just backed up my instance, created a new image in my SD card then restored my saved instance? Must be a better way?
