TLJH Installation failure

Hi,
While trying to install Littlest JupyterHub on my own server running Ubuntu 18.04, I get the following error:

Setting up JupyterHub…

It is worth mentioning that I have managed to install littlest jupyterhub on identical setup (ubuntu 18.04) two months back and it is still working today.
Issues #444 and #450 created on github seem similar to my untrained eye.
Thanks for help!

Most of the time these are dependency-issues. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works

For Python 2.x use:

$ sudo apt-get install python-dev

If you using python 3, try to replace python-dev with python3-dev

For a specific version of Python 3, replace x with the minor version in

$ sudo apt-get install python3.x-dev
