I would like just voice my support for Debian going ahead with packaging this project, if someone still has the interest (I do not have the know-how myself).
An issue has been open since August 3 and continues to garner attention from the community which is a bug preventing old-stable (and downstream distros) from working AT ALL with current AND past Signal clients (as the old versions have been blocked). It is my understanding this issue is eminently addressable by packaging. There has so far been no response from Signal maintainers, despite being directly addressed in the issue multiple times. Additionally, arguments made by the Signal developers not to have external packaging have now been proven incorrect, in large part due to the existence/lack of attention to this issue. I managed to get it working fine with the workaround by "scarf" - so, it can be made to work by performing one of the suggested build or library substitution procedures. In summary: no version available via packaging works, or has worked for as much as three months now (I don't know how recently the old versions stopped working). Please see: https://github.com/signalapp/Signal-Desktop/issues/2604 Thank you, Chris
