Building Package in PPA That Depends on a package Another PPA

[roadkillbunny]

Hi there,

I am trying to publish a python script that rotates the screen of a tablet based on the orientation of the tablet. To do this, I use xrandr, or to be more specific the python bindings called python-xrandr. But this package is only available inside the Displayconfig-gtk (https://launchpad.net/~displayconfig-gtk/+archive/ppa) PPA.

After I install python-xandr on my laptop, I can build a deb package successfully. However when I upload the source to the PPA that I want to use to publish this (ppa:kkrizka/thinkpad-x61t (https://launchpad.net/~kkrizka/+archive/thinkpad-x61t)), and add the Displayconfig-gtk PPA as a dependency.

But the build fails with the following error (buildlog (https://launchpad.net/~kkrizka/+archive/thinkpad-x61t/+build/1353660/+files/buildlog_ubuntu-karmic-i386.autorotate_0.3_MANUALDEPWAIT.txt.gz)):

Build status
Dependency wait on thallium (virtual) Retry this build

* Missing build dependencies: python-xrandr

This is my first time trying to distribute a deb using a PPA, so I'm not sure if there is a way to handle such external dependencies.

if you go the page of your ppa theres an 'edit ppa dependencies' entry at the top right where you can choose the ubuntu repositories and add ppa repositories too. i remember having this problem before and not being able to do this so i'm guessing this is relatively new, or i was previously blind to it :)

I've added the Displayconfig-gtk PPA before I uploaded my package, so it's either not working or it doesn't do anything other than display a message to others that try to add it to their sources.list.

displayconfig is gutsy whereas your repository is karmic, i imagine thats the problem. you might be better importing displayconfig into your ppa since its quite old

That does seem to have been the problem. The python-xrander package works perfectly on karmic, even though it was packaged for gutsy. But it seems that the launchpad PPA dependency requires that the release be explicitly for karmic.

I did a quick test. I've added a random PPA that has a karmic release (banshee-unstable), and tried to rebuild my package. The buildlog shows that it did contact the banshee-unstable's karmic section.

I'll try to contact the maintainer of the python-xrandr package to see if he is planning to update his PPA to karmic. If not, then I'll probably fall back to uploading it myself.

Thank you for your help.
