Hi

There might be an interesting problem - whether distros like  Debian/Ubuntu 
noticed the switch to:

https://github.com/device-mapper-utils/thin-provisioning-tools


I think you may possibly need to do a gentle ping to maintainers of the 
original tool based on now outdated:

https://github.com/jthornber/thin-provisioning-tools

started to package newer version of these tools.

(Possibly there should be a much much bigger reference to new repo :) if the 
current one is blindly ignored....)
