Minimum requirements too low on oslo.log for keystone

[Dr. Jens Harbott]

After upgrading keystone from mitaka to newton-rc1 on Xenial I am getting this error:

$ keystone-manage db_sync
Traceback (most recent call last):
  File "/usr/bin/keystone-manage", line 6, in <module>

    deprecated_since=versionutils.deprecated.NEWTON,
AttributeError: type object 'deprecated' has no attribute 'NEWTON'

It seems due to the fact that the installed version of oslo.log is not updated properly:

python-oslo.log:
  Installed: 3.2.0-2
  Candidate: 3.16.0-0ubuntu1~cloud0
  Version table:
     3.16.0-0ubuntu1~cloud0 500
        500 http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-updates/newton/main amd64 Packages
        500 http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-updates/newton/main i386 Packages
 *** 3.2.0-2 500
        500 http://mirror/ubuntu xenial/main amd64 Packages
        100 /var/lib/dpkg/status

But looking at the requirements.txt in stable/newton, even oslo.log>=1.14.0 is claimed to work.

[Dr. Jens Harbott (j-harbott)]

So looking at the tags in the oslo.log repo, it seems that keystone=stable/newton needs to depend on oslo.log>=3.4.0 in order to work.

frickler, thanks again for the bug report. I just uploaded keystone 2:10.0.0~rc2-0ubuntu2 which depends on oslo.log >= 3.16.0 to align with upper-constraints and the version we have in the archive for newton.

This is a dupe of https://bugs.launchpad.net/keystone/+bug/1623168 -- it was assessed during the requirements FFE period, since there are many other versions of oslo.log that can be used.

I doubt we will do anything to our stable/newton code for this bug, we will certainly fix it in master.

[Launchpad Janitor (janitor)]

This bug was fixed in the package keystone - 2:10.0.0~rc2-0ubuntu2

---------------
keystone (2:10.0.0~rc2-0ubuntu2) yakkety; urgency=medium

  * d/control: oslo.log min version level in global-requirements is too low,
    so set min version to upper-constraints level (LP: #1628883).
