Updating Software With Pup

This chapter explains how to use the Pup graphical update program, and how Puplet works to provide notifications of available updates.

Update Notifications

Puplet works constantly in the background, checking for available software updates from the enabled repositories. When updates become available a package icon appears in the notification area, along with an alert which appears for a short time and reveals the number of updates available.

Once the notification tray icon is present, there are a number of possible actions it can perform:

• Refresh will check for new updates
• View Updates launches Pup and allows you to find more details about the packages to be updated, to de-select some updates, and to start the update process
• Apply Updates
• Quit closes Puplet until the next time the system starts

The Package Updater

This program features a scrollable text window under the heading Updates available. In this text window all of the available updates are listed, and all are selected by default. If you want to remove any of the packages queued for update, left click the ticked box next to the relevant package.

Some updates have a circular arrow icon next to them, indicating that these changes won't be applied until the next system reboot.

Further information about the updates can be found by selecting the desired package, then left clicking the Update Details text.

Once satisfied with the package selection left click the Apply Updates button. Pup checks for dependencies, ensuring that the updated packages will have everything required to function correctly. If dependencies are added a dialogue will be displayed informing you which new packages are set to be installed. Review this dialog and click Continue if it is OK.

The packages will then be downloaded and installed. If a reboot is needed for some of the changes to take place, you will be informed of this at the end of the updates.
