Read the lecture before you startPackage Management: Installing Software with apt
Update the package index, install and remove software with the Debian package manager, and inspect the package database. Graded against the dpkg database, not the terminal.
Activities
01Update the package index
Refresh apt's index so packages can be installed.
02Install the nginx package
nginx must be recorded as installed in the dpkg database.
03Install both htop and jq
Two more utilities must be present in the package database.
04Remove the pre-installed vim package
vim started out installed; remove it so it is gone from the database.
