Description Michele Baldessari 2019-02-15 13:50:35 UTC

Description of problem:
While working on porting OSP15 to RHEL8 we hit the following issue on the undercloud with glance running in a python3 based container and talking to swift (which runs via python2 inside another container). This is the full error message:

Upstream bug seems to be https://bugs.launchpad.net/glance/+bug/1772018
The following review fixes it for us: https://review.openstack.org/#/c/620234/ but there seems to be some disagreement over the correctness of the fix.

The versions used where we saw this are:
python3-glanceclient-2.15.0-0.20181226111056.c4c92ec.fc28.noarch
python3-glance-17.1.0-0.20190109134015.fb2c2e7.fc28.noarch

Comment 1 Cyril Roelandt 2019-02-19 17:11:31 UTC

OK, I'll keep an eye on the upstream fix. I think it should make its way into OSP15, so we may not even need to backport it.
