pl upload aptoncd software
aptoncd appears to no longer be maintained. It was removed from Debian a couple of years ago, and thus when we sync from Debian, it was removed from Ubuntu. The PPA hasn’t been updated for years. So I don’t think this is a candidate for being re-added into Ubuntu, sorry.
If a community volunteer (like you) decides to become a Maintainer, and re-adds the package to Debian, then it will be re-added to Ubuntu as well.
It’s a good way to contribute.
