Connecting the Tray Icon to a systemctl-started Service

jgleitze · October 11, 2020, 9:14am

I am sorry if this is already answered somewhere, but I haven’t found any forum thread, GitHub issue or documentation article about it.

What I Am Trying to Achieve

I am using duplicati on my Ubuntu device. I have multiple users on my machine. I want to run duplicati as a system service so that it runs all backups of all users, no matter which user is currently logged in.

This seems to be working, however, I cannot get the tray icon to work.

What I Tried

I added DUPLICATI_HOME="/usr/share/Duplicati" to /etc/default/duplicati and enabled the duplicati systemctl service with sudo systemctl enable duplicati. I can now access the Web UI and run backups.

Now I try to start the tray icon, but always get the same error:

Request error: System.Net.WebException: The remote server returned an error: (401) Not logged in.

I tried the following combinations:

duplicati --no-hosted-server --read-config-from-db /usr/share/Duplicati

duplicati --no-hosted-server --webservice-password <the-password>

duplicati --no-hosted-server --read-config-from-db --server-datafolder /usr/share/Duplicati/

My Questions

Does my setup make sense, i.e. is this how duplicati is meant to be used for my use case?
How can I get the tray icon to connect to my duplicati server?

Okay, I found the solution to my second question:

How can I get the tray icon to connect to my duplicati server?

The duplicati tray icon will also examine the DUPLICATI_HOME environment variable.

What I did, step by step:

Added all my users to the users group: sudo usermod -a -G users <username> (the users group already existed on my system. You can reload group assignments by running newgrp users)
Made the database file accessible to the users group with sudo chgrp users /usr/share/Duplicati/Duplicati-server.sqlite and sudo chmod g+r /usr/share/Duplicati/Duplicati-server.sqlite
Started the tray icon with

env DUPLICATI_HOME=/usr/share/Duplicati/ duplicati --no-hosted-server --read-config-from-db
