      I have issues with starting collectd in order to get my Cloudron server online again.

      Im starting a new support thread since I was unable to find another reliable support thread to use.

      Here is the Journalctl output

      root@my:/home/yellowtent/platformdata/nginx# journalctl -u collectd

              @AniTexs I think maybe the collectd config got overwritten during the upgrade. If you run /home/yellowtent/box/setup/start.sh , this will put the expected collectd config.

              Also, check the content of /etc/default/collectd . It should contain:

              LD_PRELOAD=/usr/lib/python3.8/config-3.8-x86_64-linux-gnu/libpython3.8.so

              After that, systemctl restart collectd.

                  After that, systemctl restart collectd.

                  Similar issue after upgrading from Ubuntu 20.04 to 22.04 - but despite the reference to libpython3.8.so being present in /etc/default/collectd , it seems that this file is no longer present...

                  However, what is present is /usr/lib/python3.10/config-3.10-x86_64-linux-gnu/libpython3.10.so - after referencing this file in /etc/default/collectd (i.e. adding LD_PRELOAD=/usr/lib/python3.10/config-3.10-x86_64-linux-gnu/libpython3.10.so), and restarting the collectd service, it starts running again.

                  ... but will this change persist?

                    yes, that's the correct fix. I had this line in the ubuntu 20 upgrade guide, but it's missing in the ubuntu 22 guide. I have added it now.
