Add a Personal Package Archive (PPA)

Only add software repositories from sources that you trust!

Third-party software repositories are not checked for security or reliability by Ubuntu members, and may contain software which is harmful to your computer.

Install a PPA

On the PPA's overview page, look for the heading <gui>Adding this PPA to your system</gui>. Make a note of the PPA's location, which should look similar to: <code>ppa:mozillateam/firefox-next</code>.

Switch to the <gui>Other Software</gui> tab.

Click <gui>Add Source</gui>. Enter your password in the Authenticate window.

Remove an application

Select the application and click <gui>Remove</gui>.

Software is available from third-party sources, as well as from the default Ubuntu software repositories. If you want to install software from a third-party software repository, you must add it to Ubuntu's list of available repositories.

How and where to report problems with Ubuntu.

Report a problem in Ubuntu

If you notice a problem in Ubuntu, you can file a <em>bug report</em>.

If you have a hardware issue or don't know the name of the program affected, just type <input>ubuntu-bug</input>

A new web browser tab will open to continue processing the bug data. Ubuntu uses the website <app>Launchpad</app> to manage its bug reports. If you do not have a Launchpad account, you will need to register for one to file a bug and receive email updates about its status. You can do this by clicking <gui>Create a new account</gui>.

After logging in to Launchpad, enter a description of the problem in the summary field.

After clicking <gui>Next</gui> Launchpad will search for similar bugs in case the bug you are reporting has already been reported. If the bug has already been reported, you can mark that bug as also affecting you. You can also subscribe to the bug report to receive updates about progress with fixing it. If the bug has not already been reported, click <gui>No, I need to report a new bug</gui>.

Fill in the description field with as much information as you can. It's important that you specify three things:

What you expected to happen

What actually happened

If possible, a minimal series of steps necessary to make it happen, where step 1 is "start the program"

Your report will be given an ID number, and its status will be updated as it is being dealt with. Thanks for helping make Ubuntu better!

If you get the "This is not a genuine Ubuntu package" error, it means that the software you are trying to report a bug about is not from the official Ubuntu repositories. In this case, you cannot use Ubuntu's built-in bug reporting tool.
