Found some other issues -- - most of debian/rules can replaced with a simple call to dh - missing build-dep on git (Makefile uses it to set the last-modified date) - the build of pdf does not work for el, zh_CN or zh_TN -- they should be in LANGS_NOPDF in Makefile (all the other languages in LANGS_NOPDF also still failed for me - it may be that adding a dep on texlive-xelatex and some font packages might help, possibly.) - the .gitlab-ci.yml tries to use a build-profile to disable pdf, but there's no implementation of this in debian/control or debian/rules: every CI job is currently installing texlive ecosystem, despite only building the html format a MR to fix all that is here: https://salsa.debian.org/ddp-team/release-notes/-/merge_requests/247 i can then run "gbp buildpackage --profiles=pkg.release-notes.nopdf" and it works without needing to install texlive in the chroot (given sbuild puts the chroot in tmpfs you would need a lot of memory to build all the pdfs). After the build i can dpkg-extract the .deb and view the html without having to clutter the host system at all.
