deucalion gui

Opens the app. Typing just deucalion does the same when you are on a desktop.

$ deucalion gui --help
usage: deucalion gui [-h]

open the app (also what plain 'deucalion' does)

options:
  -h, --help  show this help message and exit

Without a desktop (for example over SSH), plain deucalion prints the list of commands instead:

$ bin/deucalion
usage: deucalion [-h] [--version] COMMAND ...

If the app's libraries are missing: "The app can't start (…). The python3-gi, gir1.2-gtk-4.0 and gir1.2-adw-1 packages are needed." Install them with deucalion deps --install.

The app needs Ubuntu 24.04 or newer. On older versions it says "The app needs Ubuntu 24.04 or newer (libadwaita 1.5; this computer has 1.1). Everything also works from the terminal: run 'deucalion --help' to see the commands."

Exit codes

0 when the app is closed; 1 if it can't start.
