Comment 88 for bug 1057186

Thank you Marius for updating you PPA. It's a pity the packages are failing to build. I tried building 0.6.2.0 from source, but I've found some errors, so I decided to workaround this bug by downgrading modemmanager. I've found a very simple way for that:

1- Download Precise's modemmanager 0.5.2.0: wget http://launchpadlibrarian.net/98148167/modemmanager_0.5.2.0-0ubuntu2_amd64.deb
2- Remove current modemmanager: sudo apt-get remove modemmanager
3- Install the downloaded package: sudo dpkg -i modemmanager_0.5.2.0-0ubuntu2_amd64.deb
