Subject: [PATCH] fix(template): take the install mirror from the ports archive
 off amd64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

archive.ubuntu.com publishes amd64 and i386 only, so a ppc64el or riscv64
node was given an apt mirror carrying no package for it and the installer
could not fetch what the minimal live media lacks. The default is now the
ports archive for those architectures, chosen from the osimage's
architecture rather than the package directory, which is whatever path the
administrator configured. site.ubuntu_apt_mirror still overrides it.
