Problema na instalação do SSH? | Linux II: programas, processos e pacotes

Prezados, utilizo o Ubuntu 20.04.1, instalado exclusivamente para realizar alguns dos cursos.

Na instalação do ssh tive os seguintes logs:

Peço atenção ao final, onde se vê:

Ao tentar conectar ao outro usuário, retorna o seguinte?

acrajag@acrajag-ZenBook-UX481FL-UX481FL:~$ ssh test@localhost
ssh: connect to host localhost port 22: Connection refused

O mesmo ocorre na tentaviva de copiar os arquivos:

acrajag@acrajag-ZenBook-UX481FL-UX481FL:~/Desktop/workspace$ scp bemvindo2.txt jose@localhost:~/
ssh: connect to host localhost port 22: Connection refused

Preciso de ajuda, porque a utilização do Ubuntu está deprimente! Instalei para estudar DevOps, especificamente para o Ansible e Docker, mas seguindo toda a formação. Por ter problemas nas instalações resolvi vir para o curso de Linux antes, mas tenho os mesmos problemas aqui a partir da aula 9 deste segundo módulo (APT). Como podem ver, há pedido de ajuda em cada um dos tópicos a partir da aula 9.

Peço ajuda para compreender o que pode estar causando este problema e poder concluir o curso.

Obrigado.

O resultado foi esse gigante.

Antes de rodar a sua sugestão tentei o install novamente e apareceu que já tinha instalada a última versão. Acredito que resolveu após aquela questão do UEFI e Secure Boot em que me auxiliou no curso de Ansible (https://cursos.alura.com.br/forum/topico-vagrant-up-nao-sobe-a-maquina-virtual-141333#909955).

Aguardarei antes de marcar como solucionado, para saber se é normal tantas entradas aparecerem.

Obrigado.
