# Installs libvips-dev, preferring the distribution package and only falling
# back to a backport PPA when the distribution's own libvips is too old
# (originally Ubuntu 22.04 "jammy", which ships 8.12.x). Newer releases already
# provide a current libvips, so adding the PPA there is unnecessary and breaks
# "apt-get update" with a 404 because the PPA has no build for that codename.
