The /var/lib listing with docker in red square? The list I cited is /var and direct subfolders including lib, which you can expand if you want a comparable view of /var/lib in Duplicati.
Click on the triangle to expand, and then compare. If they’re still different, then that’s a puzzle.
Right now, these images are two different folders.
I’ve attempted to install Duplicati to Mint bypassing the docker setup to see if that lets me see the full file tree but I’ve had issues installing that too.
what version? After that, one might need to map to Ubuntu. packages.ubuntu.com shows
libappindicator0.1-cil was removed after 23.10
libappindicator3-0.1-cil was removed after 22.04
libayatana-appindicator1 is not in any version
libappindicator3-1 is available in many versions, but Duplicati isn’t requesting in your image
I don’t know what’s compatible with what. Probably need some developer input about that…
Messiness of old application indicators (used to show TrayIcon) is in the process of removal.
Duplicati 2.0.9.x Canary releases (test releases with some big changes) use a different way.
They seem to work well if one can get in to set password. Easiest way might be by tray icon. Database gets a version upgrade, but you might not have any old backups directly on Mint…
