Memulai Ubuntu

Setelah melakukan instalasi sistem operasi linux Ubuntu, pertama-tama yang perlu dilakukan adalah menginstall ifconfig dengan perintah

$sudo apt install net-tools

jika muncul tampilan seperti ini silakan update dengan perintah

root@robie-HP-EliteBook-745-G6:/home/robie# ifconfig
Command 'ifconfig' not found, but can be installed with:
apt install net-tools

$sudo apt update

Lalu install lagi dengan perintah

$sudo apt install ifconfig lalu tekan enter

akan muncul tampilan kira-kira seperti ini

robie@robie-HP-EliteBook-745-G6:~$ sudo apt install net-tools
