Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" [WWW] http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
We have instructions on debugging some types of problems at [WWW] http://wiki.ubuntu.com/DebuggingProcedures Update Notifier does the update checking and displays a neat little icon in the systray. when its checking for updates, it downloads latest package information from Ubuntu's servers, so thats why you get grey icon on the top right of the Gnome window. By default Update Notifier checks for new updates once in a day & checking updates takes about 2minutes on a internet connection with decent speed and does not consume much resources. as you have claimed it takes lots of resources, whats your system config? , make sure you have atleast 256mb ram which is required to run Ubuntu. if you meet minimum hardware requirements, try running update-manager by typing update-manager in Terminal (Application>Accessories>Terminal). and when it runs Please monitor Memory usage & CPU usage(System>Administration>System Monitor>Processes tab). And post the result here. as a temporary workaround, please disable automatic updates. here is procedure:- 1) System>Administration>Software sources 2) Navigate to Updates Tab and Uncheck "check for updates". 3) click close to exit. Please remember by this your system may be left vulnerable, as latest security updates would not be installed. to install updates you manually have to check for new update & install them regularly. use update manager to check for new updates & install them. alternatively you can use, which should be low on resource if you have a low end system. :~$ sudo apt-get update && sudo apt-get upgrade Marking it as "Incomplete" as it needs more information, which i have requested above. Please get back with required information and we would be happy to Help! ** Changed in: update-notifier (Ubuntu) Sourcepackagename: update-manager => update-notifier Status: New => Incomplete -- Update manager is extremely problematic - had to cycle power to kill it https://bugs.launchpad.net/bugs/248010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
