Advice
- Install only the packages that you will be using.
-
Update data packages by entering the command:
sudo apt-get update && sudo apt-get upgrade or sudo apt-get dist-upgrade
- If you make changes to the source list (/etc/apt/sources.list), make sure you update it using the sudo apt-get update command.
-
If you decide that you no longer need a particular package, enter the command:
sudo apt-get remove package
… Replace the word package with the name of the package you want.
- When you install a package, other packages, known as "dependencies", may be installed along with it.
Warnings
- Make sure of the reliability of the site from which you download the programs (unless it is an Ubuntu repository).
- Do not run programs that might crash your system.
