Hi Christian,
well, the messages that ask for verification are created for all Ubuntu
releases that are affected and currently still in service.
And these msgs look very similar:
The Yakkety msg:
https://bugs.launchpad.net/ubuntu/+source/mtx/+bug/1642582/comments/8
and the Xenial msg:
https://bugs.launchpad.net/ubuntu/+source/mtx/+bug/1642582/comments/9

Anyway, good that you were able to do the verification for yakkety as well
- thx for that!
