Okay, thank you.
I'm running xubuntu (Ubuntu 14.04.1 LTS).
I just updated:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install update-manager-core
and I can't get virtualbox to work. What it has seemed to come down to is that I can't download headers for the kernel I am using: 3.8.0-21-generic
because it seems to be a pretty old kernel.
I first ran sudo apt-get update, then tried the following commands and they all failed
sudo do-release-upgrade -d
sudo do-release-upgrade -p
Each of the previous commands printed the same message:
Checking for a new Ubuntu release
No new release found
I tried sudo apt-get upgrade...nothing
I tried running the update-manager from the dash multiple times...nothing
I am a recent Fedora convert coming from Ubuntu. I can manage to get around Fedora with no problems, but there are still a few things erking me...
