Assistance request: failed to communicate with subprocess mtr-packet

[garyjkuehn]

Any additional triage guidance would be appreciated. mtr was installed via homebrew on my Mac (Monterey 12.4). I've confirmed the /opt/homebrew/sbin in my path contains alias for mtr and mtr-packet in stalled in their versioned target directory /opt/homebrew/Cellar/mtr/0.95/sbin/.

I've verified the pathing. I've tried copying the executables directly the sbin directory specified within the path which all result in the same error attached.

Any suggestions are appreciated

Ehh. That's error messages implying a "probe.py" python program is having trouble....

The thing is... I'm not aware of any python code inside MTR....

Thank you. I'll review the installation of mtr-packet from pypi once again. Pip show indicates mtrpacket is 1.0.0 with no dependencies. my function for instantiating mtr-packet is:

async def probe(): async with mtrpacket.MtrPacket() as mtr: result = await mtr.probe('example.com')

If the ping got a reply, report the IP address and time

    if result.success:
        print('reply from {} in {} ms'.format(
            result.responder, result.time_ms))
    else:
        print('no reply ({})'.format(result.result))

Confirmed operation of mtr by self from terminal running sudo mtr. This runs fine. Reviewing mtr-packet. Am I mixing incompatible packages? .....
