What do I need to do to to fix this problem and update normally using dietpi-update?

(only 2 links allowed, that’s why they look like this)

Did you remember to have the ownlcoud repository added manually? Because we don’t use this for our install. Could you remove it from source file configuration??

We could check where it is located.

for i in /etc/apt/sources.list{,.d/*.list}; do echo "$i:"; cat "$i"; done

If you like to keep it, your need to update the key according owncloud desktop install doc. https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_11/INSTALL.sh

wget -nv https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_11/Release.key -O - | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/owncloud.gpg > /dev/null
echo 'deb https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_11/ /' > /etc/apt/sources.list.d/owncloud.list

Thanks for the quick reply. It worked.

I did not add any repositories manually (I am sure, since I would not know how to)

for i in /etc/apt/sources.list{,.d/*.list}; do echo "$i"; cat "$i"; done
/etc/apt/sources.list
deb http://raspbian.raspberrypi.org/raspbian/ bullseye main contrib non-free
/etc/apt/sources.list.d/mono-xamarin.list
deb https://download.mono-project.com/repo/debian/ raspbianbuster main
/etc/apt/sources.list.d/owncloud.list
deb https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_10/ /
/etc/apt/sources.list.d/raspi.list
deb htps://archive.raspberrypi.org/debian/ bullseye main
/etc/apt/sources.list.d/sonarr.list
deb https://apt.sonarr.tv/debian/ buster main

After updating the key as you described, I run dietpi-update, worked.

Minor follow up issue: vnc connection does not work any more (realvnc), client times out waiting for a response (even though server should be started automatically, config is updated).
Putty works.
All other software seems to work too.

I will have a look at the new problem later, the rest works, remote desktop is optional.

Thank you for your help!

Did you use ownCloud desktop via VNC session? At least you have this repository added to your configuration.

Sorry for the late reply.

  • Did you use ownCloud desktop via VNC session?

Not that I am aware of. Everything regarding owncloud I do either via browser or command line. I use the vnc session almost exclusively for files copying and deleting.

if not needed, you might remove that source file.
