You are using a Linux server with your administrator account, but have found that you are getting errors when you try to do some operations on the server $($that you know are correct and should work$).$ What is the most likely explanation?

Question $3$ options:

You used the wrong password.

You have a virus.

Your admin account is broken.

Linux requires privilege escalation to actually use the power of the admin account, so for some commands you will need to use a command or syntax that enables this.

You need $2-$factor authentication to execute privileged commands.
