E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)

E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

solution:

    sudo rm -rf /var/lib/dpkg/lock

    sudo rm -rf /var/cache/apt/archives/lock

    sudo apt-get update

    Finally run: sudo dpkg --configure -a to reconfigure (the system will remind)
