O Debian, Ubuntu e distribuiçes derivadas de uma dessas duas oferecem uma forma simples de instalar novos programas. Através do programa apt. Mostraremos de forma breve como utilizá-lo
Claro que você precisa estar conectado a internet.
Indico que voc primeiro edite o arquivo que controla os sites que o Debian acessa para pegar esses pacotes(chamamos assim os programas em linux)
Repositórios são os locais onde ficam salvos os programas usados pela sua distribuição Linux. Nas distribuições como like-Debian o arquivo de configuração é o /etc/apt/source.list. Editando esse arquivo podemos incluir novos repositórios ou excluí-los.
No terminal digite:
gedit /etc/apt/sources.list# deb cdrom:[Debian GNU/Linux 8.6.0 _Jessie_ - Official amd64 DVD Binary-1 20160917-14:25]/ jessie contrib main

No Ubuntu você precisa rodar esses comandos no terminal para adicionar a assinatura dos repositórios e informar para seu computador que são fontes seguras de programas:
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5044912E

apt update
apt upgrade
Na internet você encontrará variações do comando apt, como: apt-get ou aptitute. Todos eles fazem a mesma coisa e usam a mesma base de dados.
Apartir de agora você poderá procurar o programa que você deseja. podemos usar:
apt search <nome do pacote>
A saída do comando será:
apt search firefox
