    In general, it’s always best to try a simple kill without the -9 option first. This asks the process to exit normally, which allows it to clean up first. Only if the process fails to exit, meaning it’s hung, should you kill -9, which tells to kernel to terminate it.

    Another way to remove lock file in the /var/lib/dpkg/ directory is:

    $ sudo fuser -vki /var/lib/dpkg/lock
