 Personal Package Archives (PPAs) are package feeds that are not part of Ubuntu and can be used by people to distribute their own personally built packages. To use a PPA you need to first add it to your repository list and update your package sources.
+
+Some additional useful apt command examples:
+ * update package feeds:
+{{{#!bash
+apt-get update
+}}}
+ * upgrade all installed packages to their latest versions:
+{{{#!bash
+apt-get upgrade
+}}}
+ * show what version of a package is available (regardless of if its installed), for example bluez:
+{{{#!bash
+apt-cache show bluez
+}}}
+ * clean out any old packages that have newer versions installed and no longer are dependencies of anything else installed:
+{{{#!bash
+apt-get autoremove
+}}}
+ * clean out apt caches:
+{{{#!bash
+apt-get clean
+}}}
+ * remove a package (leaves its configs), for example 'bluez':
+{{{#!bash
+apt-get remove bluez
+}}}
+ * remove a package including any config files (as they normally don't get removed), for example 'bluez':
+{{{#!bash
+apt-get purge bluez
+}}}
+ * show all available packages including version info:
+{{{#!bash
+apt list
+}}}
+ * show all installed packages including version info:
+{{{#!bash
+apt list --installed
+}}}
