Question

ubuntu

Tell me
What is the difference between "sudo apt-get install build-essential gcc make perl dkms" and without dkms at the end

UPD: it didn't want to install guest addition on ubuntu in VirtualBox
found on the internet one solution was
sudo apt-get update
sudo apt- get install build-essential gcc make perl dkms
second

sudo apt-get update
sudo apt-get install build-essential gcc make perl

without explanation

Answer 1

apt-get installs ( install ) the listed programs. Therefore, the first option (with dkms) will install dkms on the system, and the second (without dkms) will simply not install dkms on the system.
And sudo simply runs the specified program ( apt-get ) as root, which is necessary when installing programs on the system.
And then you can install dkms with the command sudo apt-get install dkms
