Ubuntu developers often issue updates to the Ubuntu software. These updates may improve security or fix other problems.
When security updates are available, the Update Manager automatically starts up. For other updates you will be prompted once a week. To install updates, just click and enter your password when prompted.
The update process may take a while if many updates need to be installed.
If a pair of blue arrows appears in the panel when the updates have finished, you need to restart the computer to complete the installation.

To change how often Ubuntu checks for updates, or to set updates to install or download automatically, choose → → , and then Updates.
