Comment 1 Florian Weimer 2017-07-27 10:14:50 UTC

Also reproduces with:

koji build --scratch --arch ppc64le f27 /home/fweimer/src/fedora/glibc/glibc-2.25.90-28.fc27.1.src.rpm

I managed to defeat the anti-debugger trapper and got a backtrace:

Traceback (most recent call last):
  File "/usr/lib/python3.5/site-packages/koji/__init__.py", line 2102, in krb_login
    if self.gssapi_login(proxyuser=proxyuser):
  File "/usr/lib/python3.5/site-packages/koji/__init__.py", line 2216, in gssapi_login
    if not sinfo:
UnboundLocalError: local variable 'sinfo' referenced before assignment

Comment 2 Florian Weimer 2017-07-27 10:44:07 UTC

Unwinding further, this is caused by another exception which is suppressed:

Traceback (most recent call last):
  File "/usr/lib/python3.5/site-packages/koji/__init__.py", line 2210, in gssapi_login
    sinfo = self._callMethod('sslLogin', [proxyuser], retry=False)

  File "/usr/lib/python3.5/site-packages/requests_kerberos/kerberos_.py", line 304, in handle_response
    _r = self.handle_other(response)
  File "/usr/lib/python3.5/site-packages/requests_kerberos/kerberos_.py", line 227, in handle_other
    "{0}".format(response))
requests_kerberos.exceptions.MutualAuthenticationError: Unable to authenticate <Response [200]>

I am pretty sure I have a valid Kerberos ticket for FEDORAPROJECT.ORG, though.

Comment 3 Florian Weimer 2017-07-27 10:44:49 UTC

For submitting builds, submitting tasks through fedpkg seems to be a workaround for now.

Comment 4 Lubomír Sedlář 2017-07-27 12:46:25 UTC

This looks like this upstream issue: https://pagure.io/koji/issue/519

Comment 5 Miro Hrončok 2017-07-28 07:55:30 UTC

Marking this one as a duplicate, because the other one have more comments. Those are different Fedora versions, but apparently, the same problem.
