This page contains notes about Debian and Ubuntu packaging.

Debian

• ​Debian Package Auto-Building
• ​Debian Package Tracker
• ​Alioth.debian.org Git Repository
• ​Debian GIS Policy

Ubuntu

• ​UbuntuGIS
• ​Ubuntu Code Names

Launchpad

• ​https://launchpad.net/~grass
• ​UbuntuGIS Experimental
• ​UbuntuGIS Unstable

Requirement to upload packages:

• update OpenGPG to ​http://keyserver.ubuntu.com and then register OpenGPG in your Launchpad account

Git workflow using the GRASS specific branches

Set up building environment

Install requirements:

sudo apt-get install git-buildpackage
# on Debian also
sudo apt-get install ubuntu-archive-keyring 

Set sudo access

Run

sudo visudo

and add lines bellow:

# Cmnd alias specification
Cmnd_Alias PBUILDERS=/usr/sbin/pbuilder, /usr/sbin/cowbuilder

# User privilege specification
<username>     ALL=(root)     NOPASSWD:PBUILDERS

Configuration file

Configuration file for pbuilder (~/.pbuilderrc):

# Optionally set the architecture to the host architecture if none set. Note
# that you can set your own default (i.e. ${ARCH:="i386"}).
###: ${ARCH:="$(dpkg --print-architecture)"}

NAME="$DIST"
if [ -n "${ARCH}" ]; then
    NAME="$NAME-$ARCH"
    DEBOOTSTRAPOPTS=("--arch" "$ARCH" "${DEBOOTSTRAPOPTS[@]}")
fi
BASETGZ="/var/cache/pbuilder/$NAME-base.tgz"
DISTRIBUTION="$DIST"
BUILDRESULT="/var/cache/pbuilder/$NAME/result/"
APTCACHE="/var/cache/pbuilder/$NAME/aptcache/"
BUILDPLACE="/var/cache/pbuilder/build/"

DEBOOTSTRAPOPTS=("${DEBOOTSTRAPOPTS[@]}" "--keyring=/usr/share/keyrings/ubuntu-archive-keyring.gpg")
MIRRORSITE="http://cz.archive.ubuntu.com/ubuntu/"
OTHERMIRROR="deb http://ppa.launchpad.net/ubuntugis/ubuntugis-experimental/ubuntu $DIST main"
COMPONENTS="main restricted universe multiverse"

BUILDRESULT=/root/tmp/pbuilder-results
HOOKDIR=/root/pbuilder-hooks
EXTRAPACKAGES="${EXTRAPACKAGES} devscripts gnupg patchutils vim-tiny openssh-client lintian"
ALLOWUNTRUSTED=yes

It's a good idea to configure also lintian pbuilder hook:

mkdir ~/pbuilder-hooks
cp /usr/share/doc/pbuilder/examples/B90lintian ~/pbuilder-hooks/
sed -i 's/lintian -I --show-overrides/& --pedantic -E/; s/^su /##&/; s/^#su /su /' ~/pbuilder-hooks/B90lintian

Create chroot environment

Create specific chroot environment by (example for Ubuntu Xenial - 16.04):

export DIST=xenial
sudo -E cowbuilder --create --distribution=$DIST --basepath=/var/cache/pbuilder/base-${DIST}-ubuntugis-experimental.cow --save-after-login

Build new package

Clone Git repository

mkdir pkg-grass
cd pkg-grass
debcheckout --user <username> --git-track '*' grass
cd pkg-grass/grass

and checkout selected branch (example for Ubuntu Xenial - 16.04):

export DIST=xenial

export VERSION=7.0.3~rc2
export PATCH=1
export EXP=~exp1
export NUM=1

Update tarball (just once):

git checkout pristine-tar && git pull
git checkout ubuntugis/$DIST && git pull --rebase

Merge changes related to given tag:

git merge debian/`echo $VERSION | sed 's/~/./g'`-${PATCH}`echo $EXP | sed 's/~/./g'`
# solve changelog conflict issues
git checkout ORIG_HEAD --  debian/control debian/control.in debian/gbp.conf 

Update changelog:

# dch -v ${VERSION}-${PATCH}~exp1~${DIST}${NUM}
dch -b -v $(dpkg-parsechangelog | grep Version: | awk -F': ' '{print $2}')~${DIST}${NUM} -D ${DIST} -m "Rebuild for ${DIST}."

Check debian/control:

Provides: grass703-2

and compare the debian tag to your branch and inspect the diff in the future, it the only changes you should see are the versions for the dependencies and the git branches.

Commit changes to Git repository:

git commit -am"Rebuild $VERSION for $DIST"

Build package:

gbp buildpackage -S -sa --git-pbuilder --git-ignore-new --git-dist=${DIST}-ubuntugis-experimental >../log.packager-$DIST 2>&1

Note1: use -sa only when build/uploading first package for GRASS version

Note2: all lintian issues of severity info (I:) and higher need to be reviewed and fixed before the upload

cat ../log.packager-$DIST | awk '/+++ lintian output +++/,/+++ end of lintian output +++/' | grep -v ^+++

Tag release version in Git repository:

git tag ubuntugis/`echo $VERSION | sed 's/~/./g'`-${PATCH}`echo $EXP | sed 's/~/./g'`.${DIST}${NUM}

Upload to Launchpad

Configuration file ~/.dput.cf:

[ubuntugis-experimental]
fqdn = ppa.launchpad.net
method = sftp
incoming = ~ubuntugis/ubuntugis-experimental/ubuntu/
login = <yours-launchpad-id>
allow_unsigned_uploads = 0

Sign created package

debsign ../grass_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}_source.changes

and upload to Launchpad:

dput ubuntugis-experimental ../grass_${VERSION}-${PATCH}${EXP}~${DIST}${NUM}_source.changes

Push the package:

git push --all --set-upstream ; git push --tags

Notes

Create new branch for Ubuntu version

Create a new branch if not exists:

git checkout -b ubuntugis/$DIST debian/`echo $VERSION | sed 's/~/./g'`-${PATCH}.exp1
git push origin ubuntugis/$DIST

Update branch in gbp.conf & Vcs-Git URL, see ​example.

Build package from tarball

Warning: this part is out-dated, use Git workflow using the GRASS specific branches instead.
