Greetings Oisin.
Thank you for taking an interest in this thread.
I'm curious if your active Python is not the system installed one.

ERROR: Could not install packages due to an EnvironmentError: [Errno 13]
Permission denied: '/usr/local/lib/python3.6/dist-packages/PyQt5'
Consider using the `--user` option or check the permissions.
Therefore I tried...

Requirement already satisfied: PyQt5>=5.13 in
./.local/lib/python3.6/site-packages (from PyQtWebEngine) (5.13.0)
Requirement already satisfied: PyQt5_sip<13,>=4.19.14 in
./.local/lib/python3.6/site-packages (from PyQt5>=5.13->PyQtWebEngine)
(4.19.18)
Installing collected packages: PyQtWebEngine
*Successfully installed PyQtWebEngine-5.13.1*
Then I ran mnemosyne from the command line:
kevin@Frodo4-MSI:~$ mnemosyne
An unexpected error has occurred.
Please forward the following info to the developers:
Traceback (innermost last):
File "/usr/bin/mnemosyne", line 132, in <module>
from PyQt5 import QtWebEngineWidgets # Needs to happen first for some
reason.
*RuntimeError: the sip module implements API v12.0 to v12.6 but the
PyQt5.QtWebEngineWidgets module requires API v12.7*
An unexpected error has occurred.
Please forward the following info to the developers:
Traceback (innermost last):
File "/usr/bin/mnemosyne", line 132, in <module>
from PyQt5 import QtWebEngineWidgets # Needs to happen first for some
reason.
*RuntimeError: the sip module implements API v12.0 to v12.6 but the
PyQt5.QtWebEngineWidgets module requires API v12.7*
Noticing the RuntimeError related to '*sip*' I tried:
pip3 install PyQt5-sip
Requirement already satisfied: PyQt5-sip in
./.local/lib/python3.6/site-packages (4.19.18)
But nothing related to API v12.7
I attempted to run Mnemosyne from the command line again and received the
same (last) error message.
Again I'm stumped and I am at a loss as to how to proceed.
However I do thank you for your suggestions and assistance. It's
appreciated.
