When I run autoremove I get the following. I am in root and have tried running sudo apt install -f without luck. This issue occurred because I ran sudo apt install mongodb and realized that the command installs v 3.6 and I needed the latest version, so I used mongodb documentation to install mongodb 4.4. Any suggestions would be much appreciated!

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org-tools : Depends: mongodb-database-tools but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
mandi@mandi:~$ apt --fix-broken install
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?
apt install
not as root, i.e not using sudo. Thus their error mentions "are you root" and the solution is to use sudo. In this question the issue raised is being run as root, and the error is different, so it seems the problem must be different. – M1ke Nov 11 '20 at 17:11
