Hello Kris, Thanks for reporting this issue, I'll give it a look as soon as I can.

Hello Kris,

 Effectivly, the PPA was throwing an error when you try to install QtQR in Ubuntu Precise, because we had not uploaded the packages for that version (and for Quantal either). I'm uploading the packages right now and you should be able to install from the stable PPA in minutes. You can use the daily PPA meanwhile (https://launchpad.net/~qr-tools-developers/+archive/daily), it is safe to run that version, and has some bugs squashed ;)

Thank you very much for informing us about this issue.

Cheers!
