publishConfig_update.py: no such file or directory

[cafelinked]

I am trying to follow the documentation here, and tried running the following commands:

./publishConfig_update.py --registry http://localhost:4873

I get the following error:
bash: ./publishConfig_update.py: No such file or directory

After looking at the files, it seems that this file is no longer included?

I am new to Linux, and so any suggestions/help I would appreciate it.

Edit: It seems that I was building this from the source code rather than downloading the .deb file. I simply downloaded the .deb and installed it and it works perfectly!
