Unable to start Duplicati after installing on Debian

1

Hello,
I just installed Duplicati on my Debian 11 server, using the docs.
I followed all the steps, but every times I try to start Duplicati, it fail (sudo systemctl start duplicati.service).
Here is the result of sudo systemctl status duplicati.service :

● duplicati.service - Duplicati web-server
     Loaded: loaded (/etc/systemd/system/duplicati.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Thu 2023-11-23 11:24:15 UTC; 6s ago

And here sudo journalctl -e -u duplicati :

Thank you very much for your help!

Hello

which ones, exactly ? because there is nothing in the docs about Debian 11.

it’s not very informative. Better approach would be to look at the command line used by Duplicati (systemctl cat duplicati) and launch it from command line using sudo to get root. You would get console output.

The ones about Debian 10, in Prerequisites and Installing duplicati on linux.

gives :

# /etc/systemd/system/duplicati.service

[Unit]

Description=Duplicati web-server

After=network.target

[Service]

Nice=19

IOSchedulingClass=idle

EnvironmentFile=-/etc/default/duplicati

ExecStart=/usr/bin/duplicati-server $DAEMON_OPTS

Restart=always

[Install]

WantedBy=multi-user.target

But we see with sudo journalctl -e -u duplicati that /usr/bin/duplicati-server does not exist, and that is the issue that causes the fail of starting duplicati.

Ok I found out. It was mono packages that was not correctly installed!

why would it be so ? did you use sudo apt install mono-devel ?
