ps aux | grep -i apt

sudo kill <process_id>
# Check if the process was killed by running the ‘ps aux | grep -i apt’ command. If it is still running, force kill it with SIGKILL signal:

sudo kill -9 <process_id>

sudo killall apt apt-get

Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
