!!! Debian Packaging and System Administration in Ruby
-This show
was on March 7, 2011 at the [OSS building in Grafton Road|http://www.oss.co.nz/contacts].
+This presentation
was on March 7, 2011 at the [OSS building in Grafton Road|http://www.oss.co.nz/contacts]. First, we built packages. These packages were built on Ubuntu (Maverick) but the Debian process is probably similar.
+
+The steps below for building a package from scratch is heavily based on Daniel Holbach's excellent tutorial videos. He has quite a few videos on ~YouTube that illustrate many aspects of packaging for Ubuntu. The first of these is here: http://www.youtube.com/watch?v=zKLabbXTqMc
+
+__Checkinstall__
+
+Here are the steps for wrapping up a source package into a Deb using Checkinstall.
+
+<verbatim>
+
+wget http://www.eecis.udel.edu/~ntp/ntp_spool/ntp4/ntp-4.2/ntp-4.2.6p3.tar.gz
+tar zxvf ntp-4.2.6p3.tar.gz
+cd ntp-4.2.6p3
+./configure
+make
+
+# stop!
+# checkinstall will "make install"
+
+# copy files you want distributed with the package
+mkdir doc-pak
+cp README INSTALL COPYING ChangeLog TODO doc-pak
+
+# you can now add scripts to be run during install:
+#
+# preinstall-pak Run BEFORE the package is INSTALLED
+# postinstall-pak Run AFTER the package is INSTALLED
+# preremove-pak Run BEFORE the package is REMOVED
+# postremove-pak Run AFTER the package is REMOVED
+
+sudo su
+checkinstall
+
+# Checkinstall will ask for a package description
+# Change maintainer if you so desire
+
+less ntp_4.2.6p3-1_i386.deb
+dpkg -L ntp
+
+# to remove: apt-get remove ntp
+</verbatim>
+
+__The Full Package__
+
+These are the steps we followed to produce a complete Ubuntu package.
+
+<verbatim>
+Set up environment
+------------------
+apt-get install devscripts build-essential fakeroot debhelper gnupg pbuilder dh-make lzip
+
+vi ~/.bashrc
+# export DEBEMAIL="leslie.viljoen@gmail.com"
+# export DEBFULLNAME="Leslie Viljoen"
+
+source ~/.bashrc
+export | grep DEB
+
+gpg --gen-key #use defaults, enter name, email, password
+gpg --list-keys
+
+# you can now upload your key on launchpad.net
+# good idea: backup your key (Ubuntu One?) and remember password
+
+vi ~/.pbuilderrc
+# COMPONENTS="main restricted universe multiverse"
+
+sudo pbuilder create #169 MB in /var/cache/pbuilder
+
+
+Create package
+--------------
+# almost same process: watch Daniel's vids
+# vids are slightly out of date
+
+wget ftp://ftp.gnu.org/pub/gnu/ed/ed-1.5.tar.lz
+tar xvf ed-1.5.tar.lz
+
+# this archive name is very important...
+# you must use underscore and .orig
+# you must make a gzipped tar
+tar czf ed_1.5.orig.tar.gz ed-1.5
+
+cd ed-1.5
+head COPYING
+dh_make -s -c gpl3 #single package, gpl license
+cd debian
+rm *.ex *.EX docs info README.Debian README.source
+
+vi changelog
+# version -> 1.5.1-0ubuntu1
+# maverick
+# Initial release (no bugs closed)
+# Repacked .tar.lz to .tar.gz, no other changes
+
+vi control
+# section: editors
+# remove stuff
+# copy in Description from README
+
+vi copyright #critical!
+# downloaded: ftp://ftp.gnu.org
+# less authors
+# find . -name '*.c'|xargs grep Copyright
+
+cd .. #package directory (ed-1.5)
+debuild -S -sa #source only package, include orig src
+
+# may change things and run debuild again
+# man pages all over, millions of options
+# produces:
+# new source .tar.gz
+# .dsc file, tying .orig to new source .tar.gz
+# debuild used to make .diff, now see:
+# http://wiki.debian.org/Projects/DebSrc3.
+#
+
+cd .. #to where new .dsc file is
+sudo pbuilder build ed_1.5-0ubuntu1.dsc
+less /var/cache/pbuilder/result/ed_1.5-0ubuntu1_i386.deb
+
+# depends has been created for us
+# this is very simple, you have to add a lot more
+# stuff to make a real package: mostly documentation
+# you'll be communicating with upstream and ubuntu
+# irc: #ubuntu-motu on freenode
+
+</verbatim>
+
+__Modifying a Package__
+
+We did not show these steps in the presentation, but they can be followed to introduce a small change into an existing package.
+
+<verbatim>
+
+# make sure you have a source repos in /etc/apt/sources.list
+grep deb-src /etc/apt/sources.list
+
+apt-get source tango-icon-theme-extras
+# the source has been extracted and ubuntu diff applied
+# according to the dsc file
+
+cd tango-icon-theme-extras-.1.
+vi debian/control
+# update standards to 3.7.3
+# add Homepage field
+
+# now document changes
+dch -i
+
+# to upload to Ubuntu, build source package
+# because its a patch, do not force including of original source (-sa)
+debuild -S
+
+# to build binary for yourself
+apt-get build-dep tango-icon-theme-extras
+debuild
+
+# to install
+cd ..
+sudo dpkg -i tango-icon-theme-extras_.1.-0ubuntu5_all.deb
+
+# if dependencies were missing, apt can pull them in
+# automatically and complete the installation:
+sudo apt-get -f install
+
+</verbatim>
