I am currently updating from Nextcloud on my Pi from Version: 19.0.5 to 20.0.4.
I tried it twice and I had the same problem:
Nextcloud is not installed - only a limited number of commands are available
Command "upgrade" is not defined.
I am upgrading via the webinterface but also updating directly on the pi does not seem to solve the problem. Has anyone faced similar issues when updating to version 20.X.X ?
How did you install Nextcloud? (link to docs or image used)
Log content can help finding the problem, Check your logs and share them if relevant and need support.
I used this link
for the first installation. Afterwards I just used the nextcloud web panel for updates etc.
Anyway I just scrolled through my logs and there were to many errors from the last day… I think it is beyond a reasonable fixing point…
I think I should just make a new setup. It seems easier and faster.
Thanks anyway
