Debian packaging now done in docker, see https://github.com/obspy/obspy/tree/master/misc/docker#2-obspy-deb-packaging-based-on-docker

Here is a short walkthrough for doing the Debian packaging of ObsPy. It uses chroot/schroot and debootstrap to build packages for all distributions and architectures on a 64bit Debian host.

• Create schroot/debootstrap environments:

# add testing to sources.list, we need a more recent debootstrap that knows
# the more recent ubuntu releases...
sudo cat >> /etc/apt/sources.list <<'EOT'

deb http://ftp.de.debian.org/debian/ testing main # REMOVE AGAIN
EOT
sudo aptitude update
sudo aptitude install debootstrap -t testing
# remove our sources.list entry again, otherwise aptitude wants to update
# all our packages...
sudo ex /etc/apt/sources.list <<'EOT'
g/REMOVE AGAIN/d
wq
EOT
sudo aptitude update
sudo aptitude install schroot debootstrap

# comment out line that mounts /home in schroot,
# no need to mount that in the guest systems:
sudo ex /etc/schroot/mount-defaults <<'EOT'
g/^\/home/s/^/#/
wq
EOT

# make the config files for schroot
sudo cat > /etc/schroot/chroot.d/squeeze_i386.conf << EOT

• clone github repository and call build script

git clone https://github.com/obspy/obspy.git $HOME/obspy
$HOME/obspy/misc/scripts/build_all_debs.sh

• now either..
  • create a new apt repository from scratch

$HOME/obspy/misc/debian/deb__build_repo.sh

• or download the current apt repository

$HOME/obspy/misc/debian/deb__download_repo.sh

• add built packages to repository

$HOME/obspy/misc/debian/deb__add_debs_to_repo.sh

• upload repository

$HOME/obspy/misc/debian/deb__upload_repo.sh
