This reverts commit 1f4fb1d7a5.
This unfortunately wasn't actually tested. Because the image-based
tests run sequentially, a prior failure in the centos-8 job meant the
ubuntu job never ran.
This is failing with
10-cache-ubuntu-tarball: line 28: DIB_LOCAL_IMAGE: unbound variable
There is also a seemingly unused variable DIB_IMAGE_LOCAL_FILE; I'm
not sure what this is doing.
For now revert, and it can be re-proposed with appropriate testing.

Use Ubuntu cloud images as the baseline for built disk images.
|
|
|
|
Overrides:
|
|
|
|
* To use a non-default URL for downloading base Ubuntu cloud images,
|
|
use the environment variable ``DIB_CLOUD_IMAGES``
|
|
* To download a non-default release of Ubuntu cloud images, use the
|
|
environment variable ``DIB_RELEASE``. This element will export the
|
|
``DIB_RELEASE`` variable.
|
|
* Use ``DIB_DISTRIBUTION_MIRROR`` to override the ``sources.list``
|
|
with an alternative mirror
|
|
* Setting ``DIB_DISTRIBUTION_MIRROR_UBUNTU_IGNORE`` to an
|
|
extended-regexp (i.e. the argument to the ``=~`` bash comparitor)
|
|
which, when matched, will *not* set that line to the
|
|
``DIB_DISTRIBUTION_MIRROR``. For example, if your local mirror
|
|
does not mirror the universe and multiverse components, set this to
|
|
``(universe|multiverse)``
|
|
* Setting ``DIB_DISTRIBUTION_MIRROR_UBUNTU_INSECURE`` updates apt
|
|
settings to allow insecure/unuthenticated repositories.
