I currently have Quantal Quetzal (12.10) and I'd like to upgrade to Saucy Salamander (13.10) via the command line. I know I can do this via the Software Center, but I'm interested in learning how to do this through the Command Line. After doing a little research, it looks like these are the commands that I need to enter. Is this correct?
I had some problems with the updates lately. It started with the update manager refusing to update because it requires installation of untrusted packages. I used : sudo apt-get update && sudo apt-get upgrade and there were errors as well and said that 0 installed or updated or removed.
yet I can run these commands at the terminal and despite seeing lots of things get upgraded then open the gui update-manager immediately afterwards and see that it has a list of updates it wants me to apply. Why is this?
