Package docker-ce is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'docker-ce' has no installation candidate
Meu primeiro pensamento foi que o Docker ainda não havia lançado um pacote para o Bionic (é muito novo), mas quando procurei "install docker-ce ubuntu 18.04", encontrei um guia que parece específico para o 18.04 e basicamente fornece exatamente as mesmas instruções - sugerindo que pelo menos funcionou para o autor:
https://linuxconfig.org/how-to-install-docker-on-ubuntu-18-04-bionic-beaver
Alguém tem alguma idéia de por que isso pode não estar funcionando para mim?
sudo apt install docker.io
funcionou para mim
