[Pulp-list] "Plugin "pulp-profile-update" can't be imported" at 2.20.0

[Konstantin M. Khankin]

Hi!

I've upgraded my clients to 2.20.0 and now each of them reports "Plugin
"pulp-profile-update" can't be imported" on any yum operation.

I took one client which was not updated and didn't have this issue and ran
"yum update":

# yum upgrade

Now this client has this issue:

# yum upgrade

*Plugin "pulp-profile-update" can't be imported*Loaded plugins:
fastestmirror, versionlock
Loading mirror speeds from cached hostfile
^C

Downgrade to 2.19.1 helps:

# yum downgrade pulp-rpm-yumplugins python-pulp-bindings python-pulp-common
python-pulp-puppet-common  pulp-consumer-client python-pulp-client-lib
 pulp-agent  python-pulp-agent-lib  python-pulp-rpm-common

I tried debugging with yum -v, yum -e 10 and with strace but can't find
difference. I added new options to the config consumer.conf but they are
commented out so should not influence. I tried to go with yum source code
to see how it imports plugins but also couldn't find an issue.

What could be the cause?

Thanks!
