Corrija o erro Cannot set LC_ALL to default locale no Ubuntu

por Fernando Mariano · Published junho 11, 2014 · Updated janeiro 5, 2017

Ao inicializar uma instância do Ubuntu Server você pode encontrar algumas mensagens de erros relacionadas à definição do locale do sistema operacional. Tive que resolver esse bug nas VMs que criei na Digital Ocean, Amazon EC2 e também no Virtual Box, porém acredito que em outros ambientes este problema possa se repetir. Abaixo as mensagens de erros encontradas:

locale: Cannot set LC_ALL to default locale: No such file or directory
perl: warning: Please check that your locale settings:
locale: Cannot set LC_CTYPE to default locale: No such file or directory

Todas as mensagens estão relacionadas à falta de configuração do locale do sistema operacional, por exemplo, na Digital Ocean as VMs são criadas com o locale em inglês. Isso ocorre pois o sistema tenta traduzir os caracteres do console para pt_BR quando se conecta remotamente por um desktop em Português.

Erros retornados quando não há locale suportado pelo computador remoto

Algumas falhas que ocorrem caso o locale pt_BR.UTF-8 não seja adicionado ao sistema:

Correção da configuração do locale com dois comandos

A correção é simples, apenas execute os comandos para adicionar e reconfigurar os locales en_US e pt_BR:

locale-gen en_US en_US.UTF-8 pt_BR.UTF-8
dpkg-reconfigure locales

1 2	locale-gen en_US en_US.UTF-8 pt_BR.UTF-8 dpkg-reconfigure locales

Faça logout e login novamente via SSH e você não receberá novas mensagens de erro.

Update para 16.10:

No Ubuntu 16.10 ficou mais fácil. Recentemente criei um droplet na Digital Ocean e recebi a seguinte mensagem já com os comandos para solução do problema:

-bash: warning: setlocale: LC_CTYPE: cannot change locale (pt_BR.UTF-8): No such file or directory
