I use hg-git to put all my Mercurial based projects on Github.
But the last OpenSUSE update installed Mercurial 5, but left the old hg-git for Mercurial 4. Now it does not work anymore.
I used to use it all the time on linux.
Unfortunately the OpenSUSE update also removed it. Completely, it is not even listed in the package management anymore.
No one wants to maintain non-mainstream software
