Ubuntu and Lubuntu notes

Notes about Ubuntu and Lubuntu (a lightweight Ubuntu).

Ubuntu is based on Debian so you may find my Debian notes useful.

Determine Ubuntu version

lsb_release -a

Reference: Checking your Ubuntu Version

Purge an application

sudo apt-get purge [package]

Purge will remove the application and its configuration files.

Add a PPA repository

PPA is a third-party archive of application packages.

sudo apt-add-repository ppa:foo/bar

Remove a PPA repository

sudo apt-add-repository --remove ppa:foo/bar

However, at the time of writing there is a bug that prevents this working properly. See apt-add-repository –remove doesn’t remove deb-src entry .

Until this is fixed you’ll have to remove them manually:

sudo rm /etc/apt/sources.list.d/foo-bar-precise.list
sudo rm /etc/apt/sources.list.d/foo-bar-precise.list.save

Where ‘precise’ is the Ubuntu release.

Reference: How do I remove a PPA added via command-line?.
