CI

Both nightlies (nautilus and octopus) started failing a week ago. The error seems to be related to the encoding used (console?), but given the job template (ceph-api-nightly/config/definitions/ceph-api-nightly.yml) is the same for all the three main branches and this is not failing in pacific...

It happens while installing teuthology package:

A difference I noticed between the last successful run in Octopus and first one failing was the addition of some package: ansible-core

At this online diff it can be observed the differences between both.

It could also be an issue in teuthology rather than in the build env?
