I am using Oracle VM Virtual Box (Version 5.1.18) to run Ubuntu 16.04. I am using proxy server . I have configured proxy settings in apt.conf and apt.config.In both these files my http proxy is set with username,password,host,address and my net is working fine. I have been able to install openjdk-8 version. My jdk version is
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)
I am trying to install java 8 using command
sudo apt-get install oracle-java8-installer
But this is the error I am getting
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
Somewhere I read I need to use command sudo apt install snapd
but this is the error it is showing

Any help would be appreciated I have been trying to install java past 1 day but couldn't.
EDIT
Also while using sudo add-apt-repository ppa:webupd8team/java.This error-
Cannot add PPA: 'ppa:~webupd8team/ubuntu/java'.
ERROR: '~webupd8team' user or team does not exist.
I have referred to this link Oracle-Java8-Installer: No installation candidate.
In first answer in this link there is no such file as webupd8team-java.list in /etc/apt/sources.list.d
While in second answer this command sudo apt-get install python-software-properties produces the same error as sudo apt install snapd
