    On the Aircrack-ng homepage you might have missed:

    Channel -1 issues

    If you are receiving an error message talking about channel -1, you either have to patch your driver like explained in the wiki or get the latest version of Aircrack-ng from our subversion repository and use the option --ignore-negative-one. You can find an installation guide also in the wiki.

    If you've already compiled this from SVN, try adding the --ignore-negative-one argument to your injection command.

    To have Gerix do that for you, you're going to need to open the script and look for where it calls aireplay (et al).

  2. Check if your driver is compatible.

    And have a look in the aircrack-ng wiki for the channel-1 issue

  3. Recently I was commissioned to teach someone how to crack wifi, the pc used to perform the wireless audit was Ubuntu 12.04. I had this same issue but was able to overcome the problem by updating the kernel from 3.2 to 3.6. This fixed the problem. I tried a patch and that was unsuccessful. Best of luck, should solve your issues.
