"BrokenPipeError" - Githubissues

Describe the bug Had a "BrokenPipError" with the default, apt installed crackmapexec in Kali. Tried to reinstall via pipx and installed the apt version. Still the same error. I guess its a problem with the setup? Otherwise other users would have brought this up. But I can't see where the problem is.

To Reproduce Steps to reproduce the behavior:

Install via pipx
Run cme smb <ip> --shares

Expected behavior Not throwing exceptions?!

as a data point I tried changing the min protocol from SMB2 to LANMAN1 and restarting smbd, it made no difference, same error
