Well, Synaptic package manager is not bundled with Ubuntu v 12.04 as it was with previous
versions of Ubuntu. However Synaptic Package Manager can be installed on Ubuntu version 12.04 through the terminal window or Ubuntu software Center. To install Synaptic Package Manager type the following command to your terminal window:
sudo apt-get install synaptic
I installed Synaptic Package Manager on my ubuntu 12.04 but after some update, it stopped working. Whenever I try to launch Synaptic Package Manager from the unity panel, it asks me to enter my root password. After entering the password, nothing happens. I tried to solve the problem but could help myself with nothing. Even restarting Synaptic from the terminal will also not work. the only solution to this problem I got is uninstall Synaptic and reinstall it. When I reinstalled, it worked fine again. To uninstall Synaptic package Manager from Ubuntu 12.04 insert the following command to terminal window:
sudo apt-get --purge remove synaptic
Now after removing Synaptic, reinstall it using the following command:
sudo apt-get install synaptic
You are done. After installing it back will solve the problem. Hope it helps you.
