OP25 Here we go again.

[MCWKen]

I was forced to rebuild the computer, and when it came to OP25, initially got many errors which I was able to solve. But this remains something I cannot resolve.

Error:

python version detected: 3.12.3 (main, Nov 6 2025, 13:44:16) [GCC 13.3.0]
main: exception occurred
main: exception:

Running Ubuntu 24.04.3

Latest Boatbod package.

Command line:

Any suggestions?
Thanks in advance,

Ken

Did you start with a fresh op25 install or copy the directories over from the old installation?
Best guess is there are remnants of an old build hanging around, either directly in the ~/op25 hierarchy or somewhere in /usr/local/lib where the shared libraries get installed. Recommend you blow it away and start over by running the ~/op25/install.sh script.

I see this:

RuntimeError: list contains invalid format!

Can you post your trunkmusc.tsv or run without it?

Tried to run:
ken@ken:~$ ./rx.py --args 'rtl' -f 774.3301250e6 2> stderr.2

Same error.

Did you see boatbod's questions? I'm assuming when you rebuilt the PC, that meant starting with a fresh OS?

If you google for "RuntimeError: list contains invalid format!" there are numerous hits for occurrences of this particular gnuradio error after some sort of update. Some mention gr-osmosdr, but either way I think it's a incompatibility between libraries - either those that you built yourself via the op25 install process or those that came in a package or were left behind from a previous install.

I do not think this has anything to do with op25 config file contents or format. Those typically produce other python errors.

I will follow the Google RuntimeError. Thanks

Ken,

Were you able to get op25 going again? If not, send me a PM and I will be willing to assist offline.
