Unable to install/upgrade packages in root terminal

Support
#1

I’m not sure if I did something wrong, but I am unable to use apt upgrade. I keep getting these error messages:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

Any help as to why this is happening would be greatly appreciated, thanks!
In case it matters, I was trying to install xorg, slim, and I3 when this happened.

Can you checking whether apt is already running ? and try killing them?

ps -aux | grep apt
kill -9 <found_pid>
