Hi.
I am personally a fan of the Debian/Ubuntu and other packages, as they immensely simplify 
the sysadmin part of my life.

But for this kind of problem, there is little that anyone on this list can do, because the 
people who so "package" Tomcat to distribute it, are not the same ones who develop Tomcat 
and provide a "standard Tomcat download" on the website at
tomcat.apache.org.

So basically here, we have no idea what this package really does, or how/where it 
distributes the various components of Tomcat.  You need to get in touch with the 
Debian/Ubuntu people for that.
These packages typically "distribute" Tomcat over a series of directories (/usr/share, 
/var/lib, /etc/tomcat etc..), which are very clever but at times quite difficult to 
follow. So here we have no idea what *should* be [/usr/share/tomcat8/common/classes] under 
Ubuntu for example, and why it is obviously not there.

All we can tell you here, is that you can download a working tomcat version 8 from 
http://tomcat.apache.org, and follow the provided instructions to install it.
And if you have a similar problem with that one, then someone here should be able to help 
you better.
