I installed a clean Kubuntu 11.10 64bit on a Dell Latitude E6500. Rebooted after install, ran the update manager Muon first thing, said apply all upgrades, and then at 57% ("Running dpkg") the progress bar freezes and that's it.
No external drive attached, plenty of space on the hard drive, and this is the third clean install attempt. (On that same computer, Ubuntu 11.10 and Mint 11 worked just fine). Any ideas?
