Estou usando o Oracle VM Virtual Box (Versão 5.1.18) para executar o Ubuntu 16.04. Eu estou usando o servidor proxy. Eu configurei as configurações de proxy em apt.conf e apt.config .Nos dois arquivos, meu proxy http é definido com nome de usuário, senha, host, endereço e minha rede está funcionando bem. Eu pude instalar a versão openjdk-8. Minha versão do jdk é
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2ubuntu1.16.04.3-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)
Estou tentando instalar o java 8 usando o comando
sudo apt-get install oracle-java8-installer
Mas este é o erro que estou recebendo
Package oracle-java8-installer 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 'oracle-java8-installer' has no installation candidate
Em algum lugar que eu leio, preciso usar o comando sudo apt install snapd
mas este é o erro que está sendo exibido

Qualquer ajuda seria apreciada Eu tenho tentado instalar o java após 1 dia, mas não consegui.
EDITAR
Também enquanto estiver usando sudo add-apt-repository ppa:webupd8team/java .Este erro -
Cannot add PPA: 'ppa:~webupd8team/ubuntu/java'.
ERROR: '~webupd8team' user or team does not exist.
Eu me referi a este link Oracle-Java8-Installer: Nenhum candidato de instalação .
Na primeira resposta deste link, não há esse arquivo como webupd8team-java.list in /etc/apt/sources.list.d
Enquanto na segunda resposta, este comando sudo apt-get install python-software-properties produz o mesmo erro que sudo apt install snapd
