According to your log your issue is not with XWiki but with tomcat.
Maybe tomcat8 is not available in 14.04 or your have some more complex
issue with tomcat. There is a tomcat7 based package of XWiki too.

 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-common : Depends: xwiki-enterprise-common (= 8.2)
 but it is not going to be installed
                                    Depends: tomcat8 but it is not
 installable

 *It's bizarre.  A few co-workers are stumped as well.  Perhaps I'm not using
 the correct repository?*
 *This is what I ran to add the repository:*
 wget -q "http://maven.xwiki.org/public.gpg" -O- | sudo apt-key add -
 sudo wget "http://maven.xwiki.org/stable/xwiki-stable.list" -P
 /etc/apt/sources.list.d/
 *I then ran sudo apt-get update.   Here is the output of apt-cache search
