Public bug reported:
[ Impact ]
The current Desktop for Raspberry Pi images are "full fat" images
including libreoffice, rhythmbox, shotwell, etc. Just as the PC desktop
image now defaults to a "slim" installation, and given the space issues
in producing the desktop images (LP: #2103735), we should switch the
desktop-raspi seed to derive from desktop-minimal instead.
Partly, this will alleviate our image building issues, but it also gives
users more choice in what they want in their installation (as
uninstalling seeded applications currently will result in removal of the
desktop-raspi seed, which in turn makes ubuntu-raspi-settings-desktop
removable, with all its tweaks for the Pi's hardware).
[ Test Plan ]
To check fresh installs:
* Build local test images with updated seed:
* sudo snap install ubuntu-image --classic
* git clone lp:ubuntu-images
* mkdir output
* sudo ubuntu-image classic -v -O output/ ubuntu-images/ubuntu-pi-arm64.yaml
* Flash output/*.img to test card
* Boot test card and run through initial setup
* Ensure desktop operates normally afterward
To check upgrades:
* Install oracular on test card
* Boot test card and run through initial setup
* Run through do-release-upgrade --devel
* Expect applications like libreoffice, rhythmbox, shotwell, etc. to be removed
* Ensure desktop still operates normally after upgrade
[ Regression Potential ]
The removal of default applications should be release-noted as it may be
surprising to some users, and they should be informed of how to easily
re-install any applications they miss.
Otherwise, the risk appears relatively low: other desktop images have
already switched to the -minimal seed, and the main desktop seed doesn't
appear to have anything "vital" in it. Furthermore, we're reducing the
default image size rather than increasing it, so there's little/no risk
of causing out of space issues on anyone's devices.
