I am currently running Canary 2.0.9.101 on Ubuntu 24.04. I’m on Canary since at the time it was to get away from mono that had a 24.04 issue and the Canary used .net instead.
I would like to get on to the latest stable. What version is that and can I do it safely as an update?
Nine months old is ancient in Canary time. I had to do some research on that.
The duplicati.com Downloads page currently has a Ubuntu entry that links: duplicati-2.1.0.5_stable_2025-03-04-linux-x64-gui.deb
I think need to uninstall first went away in an earlier Canary, but stop Duplicati.
Your Canary is one version short of when mandatory password came in. Read
If you use only TrayIcon, password isn’t needed. See directions for other uses.
2.1.0.5 lacks some fixes that the later Canary releases such as 2.1.0.111 have.
A notable one fixes duplicati with --no-hosted-server. I don’t know your use.
I don’t use trayicon. I just interact through the webpage at localhost:8200 with no password needed. It runs as a service when it started today journalctl just shows
Started duplicati.service - Duplicati web-server
I do have an old note with an encryption password, I don’t even know if it applies to this machine, I run duplicati on several machines. So what should I do? stop duplicati and dpkg the stable version?
You’ll need one if you even go from 2.0.9.101 to v2.0.9.102_canary_2024-08-02:
This build changes authentication for the WebUI
With this build it is no longer possible to use the web-UI without a password.
If no password is set, a random password is generated.
For users activating the UI via the TrayIcon, this will automatically log in, as the TrayIcon hosts the server.
For users that rely on the WebUI without the TrayIcon, as special link is emitted during startup that allows login.
For both cases, the password can be (re-)set with --webservice-password=... as a startup commandline argument.
This and more is described in the user manual section I linked earlier. Please read.
This isn’t an encryption password. It’s an access password for using web interface.
Might as well, but be prepared to add a password. Since you know journalctl, there’s probably a five-minute-expiration link that you can use to get in first time.
Temporary signin token explains that, but for some reason doesn’t also suggest Settings page is a good way to set a password directly into the server database.
