Mint 18 installation comments

SUMMARY

I used Umbrello and its Ada95 code gen capability many years ago.  I'm trying to use it again under Mint 18, Cinnamon version 3.07, Linux Kernel 4.4.0-21-generic.

It doesn't save a simple diagram.  

I've attached the comments from others who have tried to install Umbrello via the Mint distribution.  It seems others have this problem.

Is there a fix?  Someone mentions an older version that works with Mint but I can't find it to download.

Thanks.

 
STEPS TO REPRODUCE

Install Umbrello on Mint 18.
Run it.
Add a class to a class diagram.
Try to save the diagram.

SOFTWARE/OS VERSIONS

Mint 18
Cinnamon version 3.07
Linux Kernel 4.4.0-21-generic.

ADDITIONAL INFORMATION

I know its a KDE tool but I've never run KDE and Umbrello has worked before.  Plus, an older version of it works under Mint according to the comments on the installation page.  I would be happy to just use that version if I knew what it was and where to get it.
