Can't connect to Wifi ("Failed to change network settings")

[zaneclaes]

Describe the issue you are experiencing

Long time user of HA, attempting to install for the first time via HASS (Raspberry Pi imager installation).

After initially configuring a headless install via an ethernet connection, I cannot finish setup (i.e., change over to Wifi).

The error is:

Failed to change network settings
Object does not exist at path '/org/freedesktop/NetworkManager/ActiveConnections/6'

The connection number at the end changes (I have tried 2 installs on 2 RPis connecting to 3 different WiFi networks).

Note that the Wifi network is detected and signal strength is 100%. I enter my WEP password and attempt to save, which is when I see the error:

What operating system image do you use?

Home Assistant OS 15.2 (RPI 4/400)

What version of Home Assistant Operating System is installed?

Did the problem occur after upgrading the Operating System?
