Unable to lock the administration directory Problem
Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?

You can delete the lock file with the following command:
	sudo rm /var/lib/apt/lists/lock
You may also need to delete the lock file in the cache directory
	sudo rm /var/cache/apt/archives/lock
 sudo rm /var/lib/dpkg/lock
	After that, try opening Synaptic again.
