I use the same thing, and what you can do to get the Argon script working with Umbrel:
- Flash Umbrel using the usual way
- SSH into the Raspberry Pi (umbrel@umbrel.local or umbrel@IPaddress (example:
umbrel@192.168.0.105)
2a) If you haven’t set the password, the default password ismoneyprintergobrrr - Install the Argon script and it should be running alongside with Umbrel.
