Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" 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.
If your current system is buggy then it is not a good idea to upgrade. The title of your bug mentions AppArmour but you filed the bug against xorg. You said "I went on https / wiki / Ubuntu. org but without results." Are you reporting a bug or looking for help? We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures. At a minimum, we need: 1. The specific steps or actions you took that caused you to encounter the problem. 2. The behavior you expected. 3. The behavior you actually encountered (in as much detail as possible). Sometimes it is better to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at http://askubuntu.com or https://ubuntuforums.org. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs. Assigning to "Ubuntu" pending reassignment to the correct package and also marking as "Incomplete" for now. ** Package changed: xorg (Ubuntu) => ubuntu -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1637711 Title: DebuggingApparmor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1637711/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
