-
- The syntax is different,
- apt-get [opt] command [things]
- Where command is:
- update - Resyncronize the package files from their sources
- upgrade - Smart-Download the newest versions of all packages
- dselect-upgrade - Follows dselect's changes to the Status: field
- and installes new and removes old packages
- dist-upgrade - Powerfull upgrader designed to handle the issues with
- a new distribution.
- install - Download and install a given package (by name, not by .deb)
- check - Update the package cache and check for broken packages
- clean - Erase the .debs downloaded to /var/cache/apt/archives and
- the partial dir too
