This avoids us having apt cache files in the final image.
For auto/build, we move the call to clean_debian_chroot to the end,
this also takes care of the caches generated by apt-get update
in case of a preinstalled-pool.
For layered, it's just a simple swap of the lines.
LP: #1826377
commit a993592 introduced an additional call to create_manifest
(and snap-seed-parse) to write binary/boot/filesystem.packages. This
caused duplicate snap lines in the qcow manifest. This is because the
live-build/auto/binary code assumes that after 'lb binary' is run the
filesystem.packages will only have debs and it calls snap-seed-parse to
add them to the file. The commit changed filesystem.packages in the
ubuntu-cpc uefi binary hook to include debs and snaps.
This patch keeps the intent of the prior patch, updating the
filesystem.packages file for the content of the uefi disk image, but
only writes a listing of debian packages to match the expected content
of filesystem.packages. The snaps will still be added in generic code
in live-build/auto/build.
When the "snap-tool" script encounters a core snap it will switch to
the "stable" channel if the channel was set to "stable/ubuntu-X.X". This
ensures that core snaps always come from one canonical source.
UbuntuStudio image builds have recently begun failing as a result of adding a
grub theme customization to their flavor, which they then try to apply by
running update-grub from their maintainer scripts. This fails with:
Setting up plymouth-theme-ubuntustudio (0.57) ...
update-alternatives: using /usr/share/plymouth/themes/ubuntustudio-logo/ubuntustudio-logo.plymouth to provide /usr/share/plymouth/themes/default.plymouth (default.plymouth) in auto mode
update-alternatives: using /usr/share/plymouth/themes/ubuntustudio-text/ubuntustudio-text.plymouth to provide /usr/share/plymouth/themes/text.plymouth (text.plymouth) in auto mode
update-initramfs: diverted by livecd-rootfs (will be called later)
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
dpkg: error processing package plymouth-theme-ubuntustudio (--configure):
installed plymouth-theme-ubuntustudio package post-installation script subprocess returned error exit status 1
Packages providing grub themes should be able to call update-grub from their
maintainer scripts, and they should be able to be installed under
livecd-rootfs. It's surprising to me that this hasn't been a problem before
now for any flavors.
We know that grub-probe should not be called as part of an image build, so
just use our standard helper function to divert it before running the chroot
stage and undivert it after.
When the magic-proxy script could not find a valid InRelease file for the
configured timestamp, it would fall back to serving the canonical version
of it. This meant that builds would succeed, even though snap-shotting the
repository failed.
This update makes the script return HTTP 404 when an InRelease by-hash
link for a given combination of mirror, suite and timestamp cannot be
found.
Installing policyrcd-script-zg2 doesn't quite do this because of the way
that live-build installs its own temporary version of policy-rc.d. The
only remotely sensible way I can see to deal with this is to create the
symlink manually.
