在Ubuntu Trusty上安装openjdk-7-jre时出错

Question

On install I get this:

Unpacking openjdk-7-jre-headless:amd64 (7u51-2.4.6-1ubuntu4) ...

Finally followed by this:

Errors were encountered while processing:
 ca-certificates-java
 openjdk-7-jre-headless:amd64
 openjdk-7-jre:amd64
 icedtea-7-jre-jamvm:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've tried:

apt-get autoclean
apt-get clean
apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get -f install
dpkg --configure -a

To no avail. I've purged every package it complains about. I've removed the packages from /var/lib/dpkg/info manually. No idea how to proceed!

Answer 1

mkdir -p /usr/share/man/man1 && \
(echo "deb http://http.debian.net/debian jessie-backports main" > /etc/apt/sources.list.d/backports.list) && \
apt-get update -y && \
apt-get install -t jessie-backports openjdk-7-jdk -y

Answer 2

While setting up Java on my chromebook, I found this site that made my life a TON easier. Here is the link DigitalOcean Java for Ubuntu with relevant part below.

To install OpenJDK 7, execute the following command:

sudo apt-get install openjdk-7-jre 

This will install the Java Runtime Environment (JRE). If you instead need the Java Development Kit (JDK), execute the following command:

sudo apt-get install openjdk-7-jdk

I've never had any issues over the many installs that I've ended up having to do after countless powerwashes for my chromebooks.

I hope this helps out.
