Ubuntu: add base repos to Kolla container image earlier #733
Conversation
Previously when building Kolla container images for Ubuntu it was common
to get a dependency error during apt package installation, such as:
The following packages have unmet dependencies:
libc6-dev : Depends: libc6 (= 2.35-0ubuntu3.1) but 2.35-0ubuntu3.4 is to be installed
This is caused by the packages in the Ubuntu base image being newer than
those in the release train repository snapshot.
This change fixes the issue by switching to the release train
repositories earlier in the build process, before the first apt command
runs.
It's possible that we may also need to pin the Ubuntu base container
image, but that would be another thing to maintain, so let's try without
for now since this approach is necessary and may be sufficient.
There was a problem hiding this comment.
I like that we're going to have this resolved for our images, but it's possibly worth noting somewhere (docs maybe) that the problem will remain for places that aren't using our images & bifrost provisioning. I know some places e.g. eidf, this has come up before but I don't know exactly how common it is

Tested and working for glance-api and nova-compute images. |
This is for the container images rather than the overcloud host images. It's only a problem if you use repository snapshots rather than upstream Ubuntu. |
