Every Nightly Build of 13.04 has recently been Failing the DELL UEFI Security Check A.K.A. Secere Boot, and I refuse to Disable Dell UEFI Secure Boot just to run the Latest Nightly Build of Ubuntu, as I would be putting myself at a huge Security Risk if I were to get some kind of Virus/Malware that Targets Linux, Just FYI. I will return to Ubuntu Nightly Build Testing just as soon as Canonical fixes their Secure Boot Problem.
