I am using Ubuntu 12.04 right now. If I use command
sudo apt-get dist-upgrade will that upgrade my ubuntu to 12.10? Does that mean I am not using the LTS version after that? I don't want to use Ubuntu 12.10 because I already tried it and it's very heavy for my netbook.
You can read the man-page of apt-get to see what each command do.
Open the manual
Find the section dist-upgrade and read
Also , read this question here: What is “dist-upgrade” and why does it upgrade more than “upgrade”?
In order to upgrade the Ubuntu release to a newer , you have to run in terminal
We read from the man-page
If you do not want to upgrade to non-LTS versions, follow these steps:
you cannot jump from 12.04 to 13.04 directly you would have to have update manger set to normal then do
sudo apt-get dist-upgrade or sudo do-release-upgrade
the difference between the commands is that dist-upgrade wants you to change your config files during the upgrade
they both will upgrade your dist when the time comes sudo apt-get upgrade only upgrades the software on your system it does not install or remove packages like dist-upgrade
