Mnemosyne doesn't run on new Ubuntu 20.04 installation

[mdp...@gmail.com]

I recently installed a fresh Ubuntu 20.04 OS and installed Mnemosyne from Synaptic.

I get the following message when I try to run Mnemosyne:

-------------

Warning: Could not import OpenGL. Might cause a black screen on some Linux distributions. Try installing python3-opengl in that case.
Log body:
 An unexpected error has occurred.
Please forward the following info to the developers:

Traceback (innermost last):

    from gtts import gTTS
 ModuleNotFoundError: No module named 'gtts'

and then there are several more messages regarding gtts missing.

I have Python 3.8.2 installed.

Hi,

You need to install gtts: sudo pip3 install gtts

Cheers,

Peter
