Does that install dependencies? I thought that was a dpkg omission. The apt command can, however Duplicati actually recommends installing `mono` directly from that project per [manual](https://docs.duplicati.com/en/latest/02-installation/#prerequisites), however since manual stops at Ubuntu 20.04 (needs update) you can get some advice [here](https://forum.duplicati.com/t/ubuntu-18-04-lts-could-not-load-file-or-assembly-netstandard-version-2-0-0-0/17050/11).

It looks like your distro might have (via Ubuntu) mono 6.8.0.105 which is 2020, so a [little old](https://www.mono-project.com/docs/about-mono/releases/), although changes are few these days. Duplicati is in the process of ending its usage of `mono`.

An alternative to `apt` is probably to install from your file browser which might install by `gdebi`.

[Duplicati 2.08.1-1 search gtk-sharp2…](https://forum.duplicati.com/t/duplicati-2-08-1-1-search-gtk-sharp2/18879) might be the next thing that the new LM 22 is missing, possibly due to a move to GTK 3. II don’t know if libgtk-sharp3 could easily work in its place.

Regardless, if 2.0.8.1 fails there, there are test releases such as 2.0.9.104 Canary and others
