In the past, we'd directly snap install lxd which defaults to
the latest/stable channel. However, whilst working on enhancing
unminimize, it was observed that we install this snap from
the stable/ubuntu-<version> channel instead.
This was also noted as a failure when running the CTF tests:
`lxd installed from latest/stable, not stable/ubuntu-23.10`
With the introduction of the 6.5 kernel for mantic on 13th September ago we are seeing image build failures
on the armhf builds. The build failure was `No kernel output for generic-lpae!`.
Introduced in the 6.4 kernel and therefore now also in 6.5 there is no generic-lpae flavor anymore. it's just generic now.
As such this commit updates the expected flavour for armhf to generic.
In a minimized image, the linux headers are stripped, so when
unminimizing it, we should restore those stripped headers
by installing the linux-virtual package.
The unminimize script previously just restored the system documentation
and translations, man pages, and installed ubuntu-minimal and ubuntu-standard
packages to provide the familiar Ubuntu minimal system. But such an image
never became an equivalent of base image.
Upon investigation and looking at how the base image is constructed -
https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/config#n1108 -
we use the following things:
- minimal task
- standard task
- cloud-image task (which involves ubuntu-server)
- ubuntu-minimal package
- server task if arch != amd64
OTOH, in the unminimize script, we use the following:
(https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/build#n286)
- ubuntu-minimal package
- ubuntu-standard package
So upon running some tests, it was found that if we install ubuntu-server
(with --fix-policy flag), we get the resulting image equivalent to that
of a base image.
cf: https://warthogs.atlassian.net/browse/CPC-3033
The pi images contain redundant copies of cmdline.txt and config.txt in
the boot partition mount-point (which get hidden by the *actual* boot
partition). This commit removes those and simplifies the subarch check
(again, +raspi is the only subarch in use at this point on the Raspberry
Pi images)
Prior to dpkg/1.21.0, there was a bug where dpkg -V/--verify
couldn't list all the correct packages correctly but with
that being fix and in archive since Jammy, this works perfectly
but the syntax to report the missing files have changed. It
just prints 'missing' now. With that new format, we can now
fix the regex to simply list the packages.
With this patch, the unminimize script works flawlessly
on a minimized image.
This package is needed by ubuntu-advantage-tools for cloud images
only. u-a-t ultimately will drop this entirely in their next release.
(cf: https://github.com/canonical/ubuntu-pro-client/issues/2692)
So instead of putting this in the seeds and then having to deal
with the seed changes to Mantic (after its release) and SRU of
ubuntu-meta, I'd rather have changes in livecd-rootfs done. Once
python3-systemd dependency is dropped from u-a-t, we'll drop it
from livecd-rootfs in Mantic+, too.
For minimized images we do not want to install any recommended packages.
We can do this by setting APT::Install-Recommends to false in apt config
or by passing --no-install-recommends to apt-get install.
