[Bug 1011936] Re: cannot upgrade to 12.04

[Jean-Baptiste Lallement]

Thanks for your report.

Non-official graphics driver installed on your system are blocking the
upgrade. Please revert to an official version before trying the upgrade
again. ppa-purge may help you with this.

I'm closing this report because it is not a bug with Ubuntu.
