Install instructions for Ubuntu 24.04 LTS ('libappindicator0.1-cil' has no installation candidate)

Thank you! Hadn’t noticed that one, slight derp.

That set me up for discovery, took these instructions and modified the package to include the newer package as an optional dependency.

mkdir tmp
cd tmp
ar p ../duplicati_2.0.7.1-1_all.deb control.tar.gz | tar -xz
# edit control added ` | libappindicator3-1` on Depends line
cp ../duplicati_2.0.7.1-1_all.deb ../duplicati_2.0.7.1-1_all~hk1.deb
tar czf control.tar.gz *[!z]
ar r ../duplicati_2.0.7.1-1_all~hk1.deb control.tar.gz

This results in an installable .deb.
Running the resulting duplicati results in some errors and warnings, this could use some more investigating. Also the menu bar icon doesn’t appear automatically (webserver on port 8200 runs and I can configure back-ups).

Any pointers as what I can do to advance this further?
Specific testing? Logs?
