Spyder fails to start on Linux

See original GitHub issue

Problem Description

Installed Anaconda on Ubuntu, and it was successful.

However, when i try to launch spyder, I get an error. It is related to PyQt5. I noticed some issues related to the problem I am having: #3383 (https://github.com/spyder-ide/spyder/issues/3383) #3145 (https://github.com/spyder-ide/spyder/issues/3145)

but according to those, this issue was fixed in spyder 3.0 and up… so i am not sure what i am doing wrong…

What steps will reproduce the problem?

Trying to run spyder spyder

What is the expected output? What do you see instead?

I expect to see an spyder launched, instead i get this error:

"Traceback (most recent call last): File “/home/rmahajan14/anaconda3/lib/python3.6/site-packages/qtpy/QtWebEngineWidgets.py”, line 22, in <module> from PyQt5.QtWebEngineWidgets import QWebEnginePage ModuleNotFoundError: No module named ‘PyQt5.QtWebEngineWidgets’

During handling of the above exception, another exception occurred:
