# Updating a `deb` and adding it to LYRASIS PPA

## This page is here for archival purposes.

If you are running Ubuntu 20.04 or higher, installing a specially-compiled imagemagick is no longer necessary. We are leaving this page available in case in the future we have a need to package our own `deb` and add it to the 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](https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1447968), and more information on `openjpeg` in Ubuntu can be found [here](https://bugs.launchpad.net/ubuntu/+source/openjpeg2/+bug/711061).
