@tmortagne, I saw today an update of our XWiki 16.7.0 Ubuntu instance. I guess it was something related with the deployment you did. It seems that the update ran smoothly, but the release that appears in the footer is still XWiki Debian 16.7.0. Must I be able to find a reference to that +1 version of the packages?
Just for the record and in case it can be useful: the download was slow. I was busy at that time, and I am not sure how many minutes it took, but it was slower that for earlier updates.
Thanks!
