Comment 13 for bug 1887638

That upload apparently wouldn't have worked anyway. I built a local package with:
https://launchpadlibrarian.net/489460611/ubuntu-dev-tools_0.175~18.04.2_source.changes
http://launchpadlibrarian.net/489460619/ubuntu-dev-tools_0.175~18.04.1_0.175~18.04.2.diff.gz

and:

$ pull-lp-source hello
