In Bionic, in order to get new or newer versions of our packages in, several transitions need to occur.
* exiv2 - BUG: [[ https://bugs.launchpad.net/ubuntu/+source/exiv2/+bug/1715931 | 1715931 ]] - 0.26 and above is required to build Digikam 5.7 or later.
* libndi - v 1.4 required if we are to use that in kstars, ever.
* libzip - v 1.2 required for ark for 'better zip handling'.
+ please add others as they occur to us, or crop up.
