I did finally track down the problem.
in the most recent version of x509.py, in the definition of
'__pyasn1_gen_san_general_names' (about line 350)
there is a comment:
# pyasn1 <= 0.3.7 needs explicit unwrap of ANY container
# see https://pagure.io/freeipa/issue/7685
Apparently > 0.3.7 needs to *not* be unwrapped (I don't know what that
means) but in my version of x509.py changing line 349:
der = decoder.decode(ext['extnValue'], asn1Spec=univ.OctetString())[0]
>
der = ext['extnValue']
fixed the problem.
In case someone else comes across this.

Title:
pyasn1 error during certificate renewal
Status in freeipa package in Ubuntu:
New
Bug description:
moving from
https://answers.launchpad.net/ubuntu/+source/freeipa/+question/693774
ubuntu 18.04, 4.7.0~pre1+git20180411-2ubuntu2
python-pyasn1: 0.4.2-3
python-pyasn1-modules: 0.2.1-0.2
Certmonger failed to renew certs on time and they expired. Rolled back
the date as per various online suggestions but continually receive the
same "903 (RPC failed at server. an internal error has occurred)".
Apache error log shows a pyasn1 error (getcert list and apache log
excerpt below).
Certs are being generated and appear in the GUI under Authentication >
Certificates. 2 new certificates are created each time certmonger
tries. for krbtgt/myrealm@myrealm.com and
ldap/ipa01.mydomain@myrealm.com. Notably, trying to view the
generated certificates in the gui generates the same 903 / pyasn1
error.
