Recently I install Ubuntu 12.10, after install, I am going to update Ubuntu, so I open terminal, and write " sudo apt-get update " then more than 1 hour has spend it won't finished. Any suggestion ...
does is to update the available archives. It should download the changes which does nothing more than let Ubuntu know what updates are available. If you want to then upgrade individual packages you should issue the command
and this will update any packages that are available except for when there is a change in dependencies. This would be the case when there is a kernel update available. To perform the kernel update for 12.10 you would then have to issue the command
sudo apt-get dist-upgrade
Note that this will not upgrade the release level. It does precisely the same thing as running the normal updates in the GUI. A release upgrade done on the terminal is something completely different.
The apt-get update and upgrade commands should either run normally, or give you some error messages. To get help fixing any problems you would have to tell us what those error messages are, but as far as I can tell the only problem is that you haven't actually run the upgrade.
if you installed latest version of ubuntu i.e 12.10 , while installing it ask you
you just select these two options , then you install it done. (ubuntu has not been released updates for ubuntu 12.10)
It depends on your internet connection , I did a update while I was tethering with my phones 3G (No 4G in the area at the moment) and it took me a good 2 hours , It can spend alot of time or even a little with you have a stable fast connection
NOTE - You are already running the latest version , That is the latest version of Ubuntu so your wasting some time there , Just check Ubuntu.com once a month to see if they have updated anything or use that terminal command once a month , Until now , You have the latest
