shim-signed depends on grub-efi-amd64-signed, which in turn has
alternative depends on either `grub-efi-amd64 | grub-pc`. However to
support booting with either via shim&signed-grub and BIOS, the choice
must be made to install grub-pc, not grub-efi-amd64.
This makes images consistent with Ubuntu Deskop, Live Server, buildd
bootable images; all of which already do install grub-pc and
shim-signed.
Additionally, this will ensure that autoremove is run after installing
anything in the CPC build hooks. This is done to avoid shipping images
that include packages that are autoremovable. This will clean-up as
packages are installed and detect any breakage at build time.
LP: #1901906
As part of the backport of the 5.4 kernel for Raspberry Pi, the kernel
flavour name is changing to match that in Focal. This is to provide a
consistent name for the 5.4 kernel in both Bionic and Focal.
This effectively rolls the kernel from 5.3 to 5.4 for raspi classic
images.
* Use series files with dependency handling to generate hook symlinks dynamically
This patch currently only applies to the "ubuntu-cpc" project.
More and more logic has been going into the hook scripts to decide
under which conditions they should run or not. As we are moving
to parallelized builds of image sets, this will get even more
complicated. Base hooks will have to know which image sets they
belong to and modification of the dependency chain between scripts
will become more complicated and prone to errors, as the number of
image sets grows.
This patch, and prior, introduce explicit ordering and dependency
handling for scripts through the use of `series` files and an
explicit syntax for dependency specification.
* lubuntu: Select lubuntu-gtk-core task as well, so we get the HWE filter
applied to the explicit dependencies it has on Xorg-recommended packages.
* lubuntu: Manually install some packages that fall out due to the above.
When no channel is given for a pre-seeded snap, the channel
should be stable/ubuntu-XX.YY to match Ubuntu policy.
This patch adds the LB_DISTRIBUTION var to config/{binary,chroot}
to have a common way of determining the Ubuntu XX.YY version
number between hooks and auto/build.
