Hello! I also had this bug. I installed Kubuntu 10.10 a couple of months ago with KDE 4.5.1. I tried to upgrade to KDE 4.6 yesterday, but it told me that "ethais" is not found... (exactly what Alexis was saying).
I have dual boot Kubuntu 10.10//WIn 7 Ultimate and found another way to upgrade to KDE 4.6 beside the KPacketKit used yesterday. 1. I re-installed Kubuntu 10.10 again today 2. On Konsole: sudo add-apt-repository ppa:kubuntu-ppa/backports sudo apt-get update sudo apt-get dist-upgrade 3. Log out and log in. It worked for me. Please note that I am a newbie to Kubuntu, Ubuntu - anything related to Linux, so I don't know how to help you if this isn't working... - kuchiki14 -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase in ubuntu. https://bugs.launchpad.net/bugs/708151 Title: can't log in to KDE after upgrading to 4.6 -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
