A simple, light-weight, desktop-independent update notification applet for the system tray on apt based systems as Debian, Ubuntu or Linux Mint.
The main goal of un-applet is to provide an easy way to help users to keep their system up to date without getting in the user's way while keeping software dependencies at a minimum.
A cron job runs in the background and periodically checks for pending software updates, the applet informs you by its color about the state of your system.
Through its menu you can view the list of pending updates, check for updates and install these.

1.421 Feb 2017 11:02
major feature:
This release adds a new dialog window that allows to easily manage the list of "held" packages for both apt-get and (if installed) aptitude.

1.3.208 Jan 2017 11:46
major bugfix:
This release fixes a bug that caused un-applet to falsely report 0 available updates on some systems.
1.312 Oct 2016 22:31
minor bugfix:
Due to a bug it was not possible to use gksu with additional command line options, as for example "gksu -w" to enforce "su-mode". This has been fixed.
There is also a fix to a minor bug that allowed the user to start more than one background process (like the query for available updates or installing of software upgrades) at the same time.
1.209 Oct 2016 17:39
minor bugfix:
This release fixes a bug that in some situations could have caused an unwanted update of the package database while one or more mirror servers were not reachable.
1.108 Oct 2016 20:05
major feature:
This release fixes a number of bugs with the query for available updates: an incomapatibility with the new command line syntax in apt-1.3 which broke un-applet for users of debian testing has been resolved and a few minor bugs which could cause some upgradable packages missing from the applet's list of upgrading candidates have been fixed.
There are also two major feature enhancements: a gui dialog for editing the applet's system settings and support for using aptitude instead of apt-get were added.
1.016 Jun 2016 15:28
major feature:
This first stable release brings a number of major improvements, most important of which are:
It is now possible to select if the upgrade procedure should perform a complete or a safe upgrade (apt-get dist-upgrade vs. upgrade).
A random delay before the update of the package database was introduced to avoid too much simultaneous traffic on the mirror servers.
New tray icon themes in various sizes.
Please note: due to technical problems with sourceforge that rendered the debian repository unusable, the project had to move and is now hosted by tuxfamily.org .
Please update your bookmarks.

minor bugfix:
This release fixes a bug that could have caused false negative results when the package database was locked by another process while the cron script tried to check for available updates. Now the script tests if /var/lib/dpkg/status is locked before actually updating the package database. If it is, the call to apt-get update will be silently postponed until the script is called the next time.
