We continue to see interference between the deb packages we publish from the colcon project and efforts to package colcon as part of mainline Debian and Ubuntu. Using a high Debian-Version value mitigated the problems in most cases, but was not sufficient to eliminate all of the conflicts we're currently experiencing.
Using a debian version suffix which falls late alphabetically appears to give our packages preference by apt. If a user enables a repository which distributes packages created by the colcon project, it is likely that they wish to use these packages instead of the ones packaged by their platform.
