pncconf error on Buster and 2.8.0~pre with 7i76e (Version: UNAVAILABLE)

I am trying to run pncconf under Buster with linuxcnc 2.8.0~pre. When I get to the "done" button it reports
LinuxCNC Version: UNAVAILABLE

The first time through it created "my_LinuxCNC_machine.pncconf" and saved it but any subsequent attempt to modify it results in the error message "LinuxCNC Version: UNAVAILABLE".

I don't have an extra ethernet port at the moment so the 7i76e is not connected, so, I know that I can't test anything but it seems like I should still be able to save the modified config. I have ordered a usb3.0 to gigabit ethernet adapter so that I can dedicate the on board port to the 7i76e and run ssh over the adapter, but I don't want to mess with the basic ethernet configuration until the adapter arrives.

Am I correct that I should be able to modify the config even though I can't test it yet? (It appears to be actually saving the changes before it reports the error.) So maybe I am worrying about nothing.

can you run pncconf from the terminal and see if it gives a better error message.

Chris,

Here is the entire text from the dialog.
PNCconf encountered an error. The following information may be useful in troubleshooting:

Is this any help?

yes posting the error message helps.
Could you also post your .pncconf file too?

I haven't been able to reproduce the error yet.

Here is the .pncconf file
