I'm following the setup from https://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/ to setup my TurtleBot3 and when I try:
sudo apt-get install libc6:armhf
I get an error that says:
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
