Can you tell me which version of UEC pack you were using? the first version runs the command gksudo dpkg -i deb/*deb (when clicking install.sh) gksudo is for Gnome environment so it may give error in Kubuntu (kde environment).
Try editing the install.sh with kate and see what's written inside. if its gksudo then replace it with kdesudo . or you can run the command from terminal yourself ================ cd /home/ashabadi/Desktop/UEC-Pack/Deb/ sudo dpkg -i *deb ================ (replace location with the the folder/directory you have stored UEC Pack) it should work -- Thanking you Shahriar Volunteer, Bangladesh Linux Users Alliance http://linux.org.bd http://forum.linux.org.bd Marketing & Contents Officer, Ubuntu Bangladesh http://www.ubuntu-bd.org Endorsement: আমাদের প্রযুক্তি ফোরাম http://forum.amaderprojukti.com/ and মুক্ত.অর্গ http://mukto.org -- Ubuntu Bangladesh | http://ubuntu.linux.org.bd ubuntu-bd@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bd
