Today I came across a problem about apt-get update.
E: Could not get lock /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the list directory
This is because another process like synaptic or update had quit without clean the lock.
So .. There will be two ways to solve the problem.
1.If the process mentioned above quited without reboot,
just $ps -e |grep apt
and then.. kill them.
2.Remove /var/lib/apt/lists/lock directly..
There is no Chinese input method in my PC currently,
so..
