The following information may help to resolve the situation:



The following packages have unmet dependencies:

 openjdk-8-jre-headless : Depends: ca-certificates-java but it is not going to be installed

E: Unable to correct problems, you have held broken packages

I've searched Google and I've added repos and other suggestions, but nothing has allowed me to install Java 8 yet.

ideas?

lsb_release -a

No LSB modules are available.

Distributor ID: Debian

Description:    Debian GNU/Linux 8.7 (jessie)

Release:        8

Codename:       jessie

is this jessie? With backports

apt install -t jessie-backports  openjdk-8-jre-headless ca-certificates-java

It is not working from Jessie backports. I tried stretch and it got installed.

echo 'deb http://ftp.au.debian.org/debian/ stretch main contrib non-free' > /etc/apt/sources.list.d/stretch.list && 

apt-get update && 

apt-get install -y --no-install-recommends openjdk-8-jre-headless && 

rm /etc/apt/sources.list.d/stretch.list && 

apt-get clean && 

rm -rf /var/lib/apt/lists/*

P.S.: I used an Australian mirror since I am here. Choose the best for you from here.

this worked for me many thanks, note you got an extra 'deb' in your echo i had to remove, i am also in Oz but this should work on all repos by now, seems it was an issue with certificates for fixed list of java versions

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851667

I keep hitting this issue. Very frustrating. I have automated packer builds and when the jdk/jre are updated this issue can resurface. after much hair pulling i've found this to be fairly reliable and fully automateable.

note that you mush have a backports repo properly defined as mentioned in other parts of this page. my image came with it pre set up. yours however, may not.

1. install ca-certs from backports


2. 
   

   install jre and jdk + headless as a second command

   
   
   

   sudo apt install -t jessie-backports ca-certificates-java
   
   sudo apt-get -y install openjdk-8-jdk openjdk-8-jre openjdk-8-jdk-headless openjdk-8-jre-headless
   
   

   
   

running the two together will prompt for a Y/N response on a config file, which are annoying to automate. so they MUST be run separately if you want this to work w/o human interaction.

This works for me

apt-get install software-properties-common

add-apt-repository "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main"

apt-get update

apt-get install oracle-java8-installer
