There was no Mnemosyne available in the Ubuntu "Software Center" listings.
However version 2.4 installed from the command line.

My Ubuntu version is 18.04.3 LTS which is the latest version. (Please note
I only use LTS versions(. The Mnemosyne version it installed is 2.4

I attempted to install webenginewidgets via...
sudo apt-get install python3-pyqt5.qtwebengine
Reading state information... Done
RESPONSE:
python3-pyqt5.qtwebengine is already the newest version
(5.10.1+dfsg-1ubuntu2).
AND
sudo apt install qtwebengine5-dev
RESPONSE:
qtwebengine5-dev is already the newest version (5.9.5+dfsg-0ubuntu2)
Again mnemosyne will not run via the GUI / Desktop

I'm really struggling here and hope you could provide some detailed
instruction on how to properly install the Qtwebenginewidgets. manually if
necessary, to get Mnemosyne working properly.
I now into my 3rd week of the current semester and hope I don't fall too
far behind in using this awesome flash card tool.
Again I thank you in advance for your expertise in this matter.
Cheers
Kevin

error - QtWebEngineWidgets
Greetings Peter,
Pleased to meet you.
Following your suggestion I was able to install Mnemosyne via the package
manager via:
sudo apt install mnemosyne
However that was not without encountering errors which were eliminated when
I remove the "...2.6.1 Python3 install" via:
a) sudo python3 setup.py install *--record files.txt*
b) sudo rm -rf Mnemosyne-2.6.1-py3.6.eggudo xargs rm -rf < files.txt
c) sudo rm -rf Mnemosyne-2.6.1-py3.6.egg (From the
*/usr/local/lib/python3.6/dist-packages/Mnemosyne-2.6-py3.6.egg*/ folder)
After which I got what appeared to be a clean install.
HOWEVER:
Upon running Mnemosyne from the GUI Mnemosyne failed to launch.
Upon running Mnemosyne from terminal I got back:
kevin@Frodo4-MSI:~$ mnemosyne
An unexpected error has occurred.

Again I call upon your invaluable expertise to help me resolve this install
successfully.
Thanks and

Hi,
I would suggest you first try to install Mnemosyne from Ubuntu's package
manager. Even if it's not the latest version, it will pull in all the
dependencies, so that you'll have an easier time manually installing the
latest version.
Cheers,
Peter

Any assistance you can offer to get this package working would be greatly
appreciated.
FYI I use Mnemosyne extensive in my college pursuits, which start again,
tomorrow.
Thanks for you help
