Tired of Googling and not doing this to enough to remember so here’s my notes:
- Grab the sources
dget http://deb.debian.org/debian/pool/main/h/htop/htop_3.0.5-2.dsc - Install build dependcies
sudo mk-build-deps --install --remove - Bump the package version
dch --bpo - Test building (apt-file might help)
fakeroot debian/rules binary - Build the deb!
dpkg-buildpackage -b --no-sign
