This is not a support forum, so you will not get an answer to your question. If you want to help us resolve the underlying bug that is causing your problem, then please reopen this report and attach the output of the command sequence at the end of this reply while the error message of missing authorization is visible. 

Otherwise please turn to one of Kubuntu's user support venues http://www.kubuntu.org/support

To get some relevant information for this bug simply open a terminal and copy the entire command block. At the very end it will print the name of a file in your home directory that you can then upload to this bug report.

sudo apt-get install gdb
_dn="kdebug330785"
_d="$HOME/$_dn"
_f="$_d/muonlog"
rm -rf $_d
mkdir $_d
rm -rf $_f
touch $_f
echo "___ps aux" &>> $_f
ps aux >> $_f
echo "___env" &>> $_f
env >> $_f
echo "___dpkg" &>> $_f
dpkg -l \*muon\* &>> $_f
cd $_d
_p=`pidof qaptworker2`
if [ $_p ]; then sudo gcore $_p; sudo chown $USER:$USER core.$_p; fi
cd ..
rm -f $_dn.tar $_dn.tar.xz
tar -cf $_dn.tar $_dn
xz -9 $_dn.tar
echo $_dn.tar.xz

Please note that there's a multitude of possible causes for missing authorization, I am going to assume that your setup has not been defunct by outside means for now, as unfortunatley that would require a completely different set of information.
