ignorando o arquivo '50unattended-upgrades.wcf-dist' no diretório '/etc/apt/apt.conmf.d/' pois ele possui uma extensão de nome de arquivo inválida

I found a fix to my problem. Apparently just starting the docker works with this command: # service docker restart

Thank you so much @elijah for helping me find the issue.
