Gnome Terminal can't remove some Language items

Ubuntu 12.04
I gave the following command

sudo fuser -vvv /var/lib/dpkg/lock
sudo rm /var/lib/apt/lists/lock
sudo cp -arf /var/lib/dpkg /var/lib/dpkg.backup
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo cp /var/lib/dpkg/available-old /var/lib/dpkg/available
sudo rm -rf /var/lib/dpkg/updates/*
sudo rm -rf /var/lib/apt/lists
sudo rm /var/cache/apt/*.bin
sudo mkdir /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists/partial
LANG=C;sudo apt-get clean -o APT::Cache-Limit=25165824
LANG=C;sudo apt-get autoclean -o APT::Cache-Limit=25165824
LANG=C;sudo apt-get --purge autoremove -o APT::Cache-Limit=25165824
LANG=C;sudo apt-get update -o APT::Cache-Limit=25165824
sudo dpkg --clear-avail
sudo dpkg --configure -a
LANG=C;sudo apt-get -f install -o APT::Cache-Limit=25165824
LANG=C;sudo apt-get --fix-missing install -o APT::Cache-Limit=25165824
LANG=C;sudo apt-get update -o APT::Cache-Limit=25165824 && sudo apt-get dist-upgrade
----------------------------------------------------------------------
But Terminal can't remove the packages I got. The final result I got 4 or 5 times is :
----------------------------------------------------------------------
