Updating a deb and adding it to LYRASIS PPA

Background

Ubuntu removed JPEG 2000 support from ImageMagick since Vivid Vervet's 8:6.8.9.9-5 version. The PPA that we have created adds JPEG 2000 support back into ImageMagick for Ubuntu 16.04 and 18.04. More information on why JPEG 2000 support was removed can be found here, and more information on openjpeg in Ubuntu can be found here.

Prerequisites

Review the Ubuntu Packaging Guide. Key items needed are in the Getting Set Up section:

  • Basic packaging software:
  • sudo apt install gnupg pbuilder ubuntu-dev-tools apt-file
  • Make sure you have your GPG, if you do not, follow the instructions in the guide.
  • Setup pbuilder:
  • pbuilder-dist bionic create
  • Configure your shell with some exports for debuild:
  • export DEBFULLNAME="Bob Dobbs"
  • export DEBEMAIL="subgenius@example.com"
  • Contact Jonathan Green to get setup on the LYRASIS PPA team.

Patching source

imagemagick is used an example. If you need to only change or patch the actual source code, then you will need to use quilt. More information on using quilt can be found in the Patches to Packages section. If you are only change dependencies, or information in the debian directory of a package, quilt is not required, and if used will cause build failures.

  • Create a directory to work in:
  • mkdir imagemagick-bionic-jp2
  • cd imagemagick-bionic-jp2
  • Pull down the source:
  • pull-lp-source imagemagick bionic
  • cd imagemagick-6.9.7.4+dfsg
  • Edit files as needed
  • Document the fix:
  • dch (Make sure to change UNRELEASED to the Ubuntu release name. For example: bionic)
  • Build the package:
  • debuild -S

Uploading to LYRASIS PPA

Once the package is built successfully, you'll upload the changes file to Launchpad. For example:

  • dput ppa:lyrasis/imagemagick-jp2 imagemagick_6.9.7.4+dfsg-16ubuntu6.8_source.changes

After the package is successfully uploaded to the PPA, you'll receive an email from Launchpad. Something like this:

Accepted:
 OK: imagemagick_6.9.7.4+dfsg.orig.tar.xz
 OK: imagemagick_6.9.7.4+dfsg-16ubuntu6.8.debian.tar.xz
 OK: imagemagick_6.9.7.4+dfsg-16ubuntu6.8.dsc
     -> Component: main Section: graphics

imagemagick (8:6.9.7.4+dfsg-16ubuntu6.8) bionic; urgency=medium

  * Add jp2 support.

And you will see it in the interface for the Lyrasis PPA:
