Professor Bear - Linux Installing Packages Apt

Code for Professor Bear YouTube videos at https://github.com/nikbearbrown

Redhat and Fedora use yum

sudo apt update
sudo apt-get update
sudo aptitude update

apt-get update updates the list of available packages and their versions, but it does not install or upgrade any packages.

apt-get upgrade actually installs newer versions of the packages you have. After updating the lists, the package manager knows about available updates for the software you have installed. This is why you first want to update
Over time, updated versions of packages currently installed on your computer may become available from the package repositories (for example security updates).

sudo apt update # Fetches the list of available updates
sudo apt upgrade # Strictly upgrades the current packages
sudo apt-get dist-upgrade # Installs updates (new ones)

apt help

sudo apt-get install wajig

sudo wajig daily-upgrade # Perform an update then a dist-upgrade
(it will ask for password if needed, and do all the update, upgrade, dist-upgrade, and autoremove steps for you).

sudo wajig dailyupdate (same as apt-get update apt-get upgrade daily)

wajig new (list new packages since last update)

wajig help


less /etc/apt/sources.list

apt-cache search python # To search for a keyword

apt-cache search . # To get a list of ALL packages
