make deb fails

[Uwe Brauer]

Hi
I was forced to upgrade Ubuntu 16.04.
Due to a comple of problems I am now running only 18.04 (which ships still python2.7 and python 3.6)

I am also third party packages such as artemis, that require python2.
I am also using an old hg-git version (a topic branch by Manuel Jacob that allows to export named branches and topics (I know that newer versions of hg-git might do that as well).

I want to compile change set d782cce137fd
so I run, as I did in Ubuntu 16.04

DEB_BUILD_OPTIONS="nocheck" make deb

But now I receive 

--8<---------------cut here---------------start------------->8---
ImportError: No module named thirdparty.concurrent
Makefile:50: recipe for target 'local' failed
make[2]: *** [local] Error 1
make[2]: Leaving directory '/home/oub/ALLES/src/hg-stable'
rm: cannot remove '/home/oub/ALLES/src/hg-stable/debian': No such file or directory
Makefile:69: recipe for target 'deb' failed
make[1]: *** [deb] Error 1
make[1]: Leaving directory '/home/oub/ALLES/src/hg-stable/contrib/packaging'
Makefile:215: recipe for target 'deb' failed
make: *** [deb] Error 2
--8<---------------cut here---------------end--------------->8---

So some python2.7 package is missing, but googled and I am not sure what is missing.

Any idea

Thanks
