This seemed to work for a quick fix but on reboot Duplicati disappears.

sudo dpkg --ignore-depends=libicu -i ~/Downloads/duplicati-2.1.0.5_stable_2025-03-04-linux-x64-gui.deb

Linked Github issue is here.

Hi @Gamedirection, welcome to the forum.

I still have not figure out why Debian insists on giving each libicu package a new name, or why they do not provide a libicu-any package. If someone knows how to be future proof, let me know.

As you can see from the list, what we are doing now is just listing all the versions we know exist, and let the package manager choose one. But as new packages are created, the package breaks.
Unfortunately, the naming is not always incremental, so it is hard to support future packages.

In any case, you can ignore it, as you most likely have some version of libicu installed already.

Are there any logs? Are you running Duplicati as a service?
If running as a service, try:

sudo journalctl --unit=duplicati | less

If you are running as a desktop application, try running it in a shell with no arguments:

duplicati
