Three-Step Process1) Add (append / Edit) Repositories
Manually:sudo nano /etc/apt/sources.listOtherwise:
sudo add-apt-repository [repository name here]eg -
sudo add-apt-repository ppa:tualatrix/ppa
2) Update Sources
sudo apt-get update
3) Install
sudo apt-get install [package name 1] [package name 2] [package name n]Other / Maintenance
Remove Packages
sudo apt-get remove [package name 1] [package name 2] [package name n]
or
remove configuration files & associated directories (purging upon removal results in a subsequent “clean” install):
sudo apt-get remove –purge [package name 1] [package name 2] [package name n]
or
reserve command for removal & associated ones:
sudo apt-get autoremove
Upgrade Software
*update before upgradeGlobal command upgrade:
sudo apt-get upgrade
If dependencies error / missing, following to upgrade:
sudo apt-get dist-upgrade [package name 1] [package name 2] [package name n]
sudo apt-get dist-upgrade
Simulate upgrade command to see list of packages to be upgraded (useful to see which programs would be interfered with by package upgrade):
sudo apt-get –s upgrade
Clean Cache
delete cache, but save newest version of packages in cache (I prefer this):sudo apt-get autoclean
delete cache completely
sudo apt-get clean
Search Packages
apt-cache search [search term 1] [search term 2] … [search term n]eg apt-cache search time zone python
Check Packages Installed
LIST installed packagessudo dpkg –list
SCROLL list installed packages
sudo dpkg –list | less
SEARCH list - grep command
dpkg –list | grep [search term]
