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.
This should be used as last resort. If you use this carelessly you can end up with a broken system.

Remove your /var/lib/dpkg/lock file and force package reconfiguration.

sudo rm /var/lib/dpkg/lock

sudo dpkg --configure -a

It should work after this.
