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.
