unable to add/remove program in Ubuntu 12.04 LTS?
- by Manish Kumar Chauhan

my problem is as following:
unable to add/remove any program using either update-manager or Synaptic Package Manager or terminal
update-manager is asking for partial upgrade and while updating
software-center 5.6.2 catalog ,
there is no progress beyond the line "this is may take a moment"
synaptic is unable to obtain an exclusive lock,
similarly can't do terminal command
sudo apt-get update
if i try to break down the lock using the command
sudo fuser -cuk /var/lib/dpkg/lock;
sudo rm -f /var/lib/dpkg/lock
it turns off my monitor display and i have to restart the whole system.
note: this whole trouble started ,when i found ubuntu software-center missing after adding a repository and reinstalled it.
