[Bug 1785157] [NEW] external (letsencrypt) certs failing to parse due to pyasn1

 

Public bug reported:

attempting a clean installation of freeipa-server on bionic using
letsencrypt certs passed as arguments fails with an error similar to:

<TagSet object at 0x7fcdaff30090 tags 0:32:16> not in asn1Spec: <OctetString schema object at 0x7fcdaff30c50 tagSet <TagSet object at 0x7fcdbda4b7d0 tags 0:0:4> encoding iso-8859-1>
The ipa-server-certinstall command failed

I was able to bypass this by downgrading pyasn1 and pyasn1-modules:

rm -rf /usr/lib/python2.7/dist-packages/pyasn1
rm -rf /usr/lib/python2.7/dist-packages/pyasn1-0.4.2.egg-info/
rm -rf /usr/lib/python2.7/dist-packages/pyasn1_modules
rm -rf /usr/lib/python2.7/dist-packages/pyasn1_modules-0.2.1.egg-info
apt install python-pip
pip install pyasn1==0.2.3
pip install pyasn1-modules==0.0.9

After that, installation is able to proceed with letsencrypt
certificates passed in.
