Service always failing

Support
1

I’m running “2.0.6.3_beta_2021-06-17” as a service on “Linux 5.13.0-41-generic #46~20.04.1-Ubuntu SMP Wed Apr 20 13:16:21 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux” (Linux Mint).
The service always fails. I can do

:~$ sudo systemctl reset-failed duplicati
:~$ sudo systemctl start duplicati
:~$ sudo systemctl status duplicati

and the service starts as expected and directly fails again

Duplicati can however be started manually through the Mint main menu and as i can say so far be used to do a backup. Restore not yet tested.

If somebody could guide me to resolve this would be greatly appreciated.

thx

thx for helping @gpatel-fr

This means somehow “fatal: impossible to open socket”:

the most usual reason for socket opening error is that the socket is already open, so what gives:

sudo ss -tapnu | grep 8200 | grep LISTEN

5 
tcp   LISTEN 0      16                     0.0.0.0:8200           0.0.0.0:*      users:(("minidlnad",pid=1081,fd=8))

you are running an incompatible service that is using the port 8200.
As it don’t seem to be possible to setup it to use another port, you will have to setup Duplicati to use an available port. see Installation - Duplicati 2 User's Manual on editing /etc/default/duplicati to change the port.

Setting up different port has done it.

I set “duplicati” to run at boot to have “Duplicati.GUI.TrayIcon” showing up.

All done. Well done.

thx a lot
