How to replicate the problem: install lr-mame2016 from source

I just tried to install lr-mame2016 on my x86 build and received the message

Could not successfully build lr-mame2016 - MAME emulator - MAME 0.174 port for libretro (/home/michael/RetroPie-Setup/tmp/build/lr-mame2016/mamearcade2016_libretro.so not found).

Looks like it tries to find python2 to generate the build configuration, but it fails:

...
make REGENIE=1 VERBOSE=1 NOWERROR=1 OSD="retro" PYTHON_EXECUTABLE=python2 CONFIG=libretro  LIBRETRO_OS="unix" ARCH="" LIBRETRO_CPU="x86_64"  clean
make[1]: Entering directory '/home/michael/RetroPie-Setup/tmp/build/lr-mame2016'
GCC 9 detected
makefile:876: *** Python is not available in path.  Stop.

Install python2 , then clean up the sources folder and re-try the installation.

Well installing that helped a bit, but still ended up with the same error in the end.

New log: https://pastebin.com/11QuM5ya
I had to trim out a section to make the log under the 512KB size needed. All the lines were about compressing layouts and running python scripts.

I did see some more warnings/errors but I can't make sense of them.

If it helps to know this, right before I tried this install, I updated every package installed which included MAME2003 and MAME2010 and both of those were successful updates.

The error is specific to lr-mame2016 - maybe fixed by this PR ?. I don't have an Ubuntu 20.04 machine to check - were you able to install lr-mame2016 before today ?

@mitu
I've never tried before to install 2016 before yesterday. I just recently finished getting the matching romset and wanted to give it a go.

I'm reading the PR and I see there is a potential fix but it hasn't been incorporated into libretro if I'm reading this right. I'll see if I can work out how the fix can be incorporated but I'm still learning the terminology workings of github.
