linux - sudo apt-get update command display the error resource unavailable? -

since want update, i'm getting error of resource not available. solution this?? due this, cannot install lamp properly.

you must sure, close system package-management applications (synaptic , etc...)

then try delete lock-files:

sudo rm /var/lib/apt/lists/lock sudo rm /var/lib/dpkg/lock sudo apt-get update 

and try install package again
