I assume you mean 16.04 which is the previous LTS release.

Ubuntu 16.04 was released 2.5 years ago so ships quite old versions:
sip v4.17 and PyQt5 v5.5.1.

These versions were released way before PyQt5 switched to private copy of sip.
So you should use “import sip” instead of “import PyQt5.sip”.

Also you should not mix distro-packaged sip with PyQt5 from PyPI, and vice
versa. Install both packages from the same source.

If you are getting this error with distro packages and some third-party
application, then please be more verbose and name that application, or show us
the complete traceback.
