This protobuf version has been introduced by Change-Id: Ie610db5304707e3db9f7025037405a3af79d2ce3

[Matthew Thode (prometheanfire)]

The actual upstream file is protobuf-3.5.0.post1, but it does pass the coinstallability tests.

I've made https://review.openstack.org/522421 to test again.

This issue also hits our Quobyte CIs, example @: http://78.46.57.153:8081/refs-changes-36-502936-8/stack.sh.log.out

[Andreas Scheuring (andreas-scheuring)]

same issue with the IBM zKVM CI

[Dr. Jens Harbott (j-harbott)]

3.5.0 was removed from pypi for reasons as yet unknown, see also https://github.com/google/protobuf/issues/3942

Patches are up to requirements to either fall back to 3.4.0 https://review.openstack.org/522447 or go forward to 3.5.0.post1 https://review.openstack.org/522412

[Fellype Cavalcante (fellypefca)]

Same issue here on UFCG OneView CI (Ironic). Hope this patches got merged. :)

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/requirements 1.2.0 release.
