  after the fix for lp:1583276 was committed:

+ [Test Case]
  
  The problem occurs with the user tries to juju bootstrap with trusty. It
  appears that the trusty simplestreams metadata is incomplete [2,3] and
  leads to a failed bootstrap [4]. Creating a trusty instance via horizon
  (no juju involved) works fine and a bootstrap with xenial works also.

+ [Regression Potention]
+ 
+ This part was added specifically for the Xenial backport, including:
+ 
+ - 436-glance-fix-race-conditions.patch (LP: #1584938)
+ 
+ And chances of regression are small based on the MR feedback from SEG
+ and this particular bug already stating the issue was fixed.
