I am trying to install xwiki on Debian 8.5 using Debian packages.

I made commands (according to instruction): 1) wget -q "http://maven.xwiki.org/public.gpg" -O- | apt-key add - 2) wget "http://maven.xwiki.org/stable/xwiki-stable.list" -P /etc/apt/sources.list.d/ 3) sudo apt-get update 4) apt-cache search xwiki - all ok, I see xwiki packages

When I trying to install - 5) apt-get install xwiki-enterprise-tomcat8-mysql but result is: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

The following packages have unmet dependencies: xwiki-enterprise-tomcat8-mysql : Depends: xwiki-enterprise-mysql-common (= 8.2.1) but it is not going to be installed Depends: xwiki-enterprise-tomcat8-common (= 8.2.1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

What is the problem and how I can correct it?

When you get an error like this (which does not really say much in practice) you can try to install the package that "is not going to be installed" to get more detail on why it's not going to be installed. I don't know Debian 8.5 very well (mostly using Ubuntu on my side) but the cause of error like this is often one (or all) of the following: * this Debian version does not provide any tomcat8 package in which case the fix is to use xwiki-enterprise-tomcat7-mysql package instead * this Debian version does not provider any openjdk-8-jre-headless package in which case the fix is to install yourself some Java 8 JVM (http://www.webupd8.org/2014/03/how-to-install-oracle-java-8-in-debian.html is nice for this). In short you need to make sure you install a package that provide one of the following features: java8-runtime-headless, java8-runtime or openjdk-8-jre-headless.

Thanks Thomas! You are right! I forgot java... But for users who don't know linux very well - it is not so clearly...

Also problem, that Debian don't provide java install through packets.

Debian does provide Java as packets. It provide OpenJDK (and that's what XWiki indicate as default dependency) on which XWiki works well but I guess Debian 8.5 standard repository only provides OpenJDK up to 7.

As a result, you should execute the following commands: echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee /etc/apt/sources.list.d/webupd8team-java.list echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886 apt-get update apt-get install oracle-java8-installer

Only after this xwiki installation goes without problems.

Actually looks like you have it in jessie-backports but it's probably not enabled by default.

Thomas, you are right. Need to edit /etc/apt/sources.list and add this line: deb http://ftp.de.debian.org/debian jessie-backports main After this openjdk-8-jdk will be installing without problem. But as I said, for non-professional in linux - it is not so clearly :) Maybe will reorganize InstallationViaAPT instruction? (http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationViaAPT) For example, can be possible to rename "second step" to "third step", "first step" to "second step" and add new "first step" with something like this: ... first step - you should install or check availability of openjdk-8-jdk package. For example in Debian Jessie need to add jessie-backports to repository sources-list ... If you agree, I can do it. -- View this message in context: http://xwiki.475771.n2.nabble.com/Debian-installation-failed-tp7600759p76008...
