The same script is used for both emacs-snapshot and emacs24. Just uncomment the paragraphs, at the end, which start with 'prepare-build-from-debian-release' and 'prepare-build-from-debian-nondfsg-release' and comment the paragraph which starts with 'prepare-build-from-debian-unstable'

Been trying to get this working, so I can build a release PPA. I've removed all of the stuff associated with the snapshots, and published to this archive. But the builds are crashing at the "patch-to-news" stage.

I'd welcome any advice! I've never build packages before, so am pretty ignorant at this.

If you're too busy (as your not using it any more) no worries. I'm very grateful for the work you put in maintaining these PPAs while you did; I've used them a lot.

Hi Phil, which version of Ubuntu are you using for this? I've had same problem when trying to build Emacs 24.4 on Ubuntu 14.04.

Ubuntu 14.10 and recent Debian versions include new version of quilt program which, when called as in the rules file for Emacs build, returns relative path to the patches and not just their names. If you look at the rules file for older Emacs and Ubuntu version, the line with patch-to-news has "debian/patches/$$p" as parameter and the current one has just "$$p".

I was just building packages locally so I edited that line manually and everything went fine afterwards, but if you want to use the script above, you either need to upgrade or add a new patch function to this script that will add debian/patches/ before $$p.

Thanks, @lukatiks, that information helped me get the script running. I created a PPA for Trusty Tahr here: https://launchpad.net/~andreas-h/+archive/ubuntu/emacs

@andreas-h Is there any change you could share the version of your script as a Gist? I'd like to try and get a PPA working for 14.10. Thanks!

@theefer sorry, totally forgot. I just updated to 24.5 using the script I put at https://gist.github.com/andreas-h/1d6a8593faa051ddedfd
