echo We hope Autodesk Maya 2019 was installed successfully. 

Another thing:
there is a python incompatibility in hashlib and ssl modules between the default modules (RHEL/CentOS/Fedora) and the Debian/Ubuntu.
It is documented in 2 README files found after install in /usr/autodesk/maya2019/support/python/2.7.11

As per READMEs, you need to run this :

cd /usr/autodesk/maya2019/lib/python2.7/lib-dynload
sudo mv _hashlib.so rhel_hashlib.so
sudo cp /usr/autodesk/maya2019/support/python/2.7.11/ubuntu_hashlib.so _hashlib.so

cd /usr/autodesk/maya2019/lib/python2.7/lib-dynload
sudo mv _ssl.so rhel_ssl.so
sudo cp /usr/autodesk/maya2019/support/python/2.7.11/ubuntu_ssl.so _ssl.so
