Ubuntu 10 patches uninstall issues

Hello I’m new to IEM can someone please help me out?

I’ve installed a patch “USN-1638-2 - ubufox update - Ubuntu
10.04 - (amd64)” on a ubuntu 10.04, in the action summary I’ve noticed that following 3 files are downloaded
"xul-ext-ubufox_2.6-0ubuntu0.10.04.1_all"
“release”
"release.gpg"
afterwards the action status changed to fixed. Then I tried to uninstall the same package using the “uninstall ubuntu.deb package”, in the action parameter tab I pasted the same package name “xul-ext-ubufox_2.6-0ubuntu0.10.04.1_all” and select the "purge an ubuntu.deb package"
The action completes successfully but in my ubuntu Pc the log file shows the following:

I tried to run the command to check if this package is exist or not “dpkg -l xul-ext-ubufox” it shows that this package is still exist. I’m confused and looking forward for experts opinion.
