But fortunately, if you’re writing either an open-source package or a package used only within your organisation 1, you don’t need to be an expert to do the right thing. Obviously, we are R developers and not lawyers, and none of this is legal advice. If the package is still not found, post the complete content of /etc/apt/sources.list and the output of sudo apt-get update.The goal of this chapter is to give you the basic tools to manage licensing for your R package. If you need to modify /etc/apt/sources.list, run sudo apt-get update afterwards, then try installing again. If you only find a line like deb precise main restrictedĪnd no line with universe, add universe at the end of that line, or a separate line with precise universe, as illustrated above. Or deb precise main restricted universe multiverse Check that this file contains a line like deb precise universe You can see what repositories you have enabled in the file /etc/apt/sources.list (and in files in the directory /etc/apt/). If you have Ubuntu 12.04, make sure that you have turned on the universe repository. If you have an older release of Ubuntu, you'll need to upgrade or to get xbmc from another place. Xbmc is only available in the universe repository, only since Ubuntu 12.04 (precise). compiling from source, downloading executable binary, etc.

Find appropriate ppa according to your Ubuntu release version.

For External Repositories, Visit Ubuntu Updates and search by.

If the package that you are unable to locate is from a PPA go to the PPA and check if it is available there for your release.

To enable all repositories ( main, universe, restricted, multiverse), use the following commands: sudo add-apt-repository main Make sure you have enabled Ubuntu repositories:

The following (general) procedure helps to solve this: When apt-get install is unable to locate a package, the package you want to install couldn't be found within repositories that you have added (those in in /etc/apt/sources.list and under /etc/apt//). There are many questions about this topic.
