Hi,

I don't have an Ubuntu 18.04 system myself, but I suggest you try and reinstall 
PyQt5. Probably something is amiss there.

Cheers,

Peter

Hi,
Greetings again....

What is the error you got?

Please forward the following info to the developers:

Traceback (innermost last):

Did you use the prepackaged 2.6 from Ubuntu, or install from Mnemosyne's own 
source distribution?

I downloaded the version (2.6.1) from the Mnemosyne-proj web site and installed 
it under Ununtu 16.04 LTS. It ran well and used it regularly. As per my 
original post, it would not launch after I performed the upgrade to Ubuntu 
18.04 LTS.

Although, in part, the error message above indicates "No module named 'PyQt5'", 
I can 'locate' the PyQt5 the package in " 
/usr/local/lib/python3.5/dist-packages/PyQt5/uic/..."
It's just I don't have enough background knowledge / skill to know whether this 
is correct, or to debug the error messages.

I'd suggest trying the official package first.

To that end, How does one properly and cleanly uninstall Mnemosyne and the 
other dependencies?

Subject: [mnemosyne-proj-users] Mnemysone will not launch under Ubuntu 18.04

Greetings all.

Last week I performed an upgrade of my Ubuntu OS from 16.04 LTS to 18.04 LTS.
Mnemosyne simple will not launch.
I'd like to do a complete uninstall / re-install, however I do not know how to 
do this, or whether it's necessary.
Has anyone else had this problem?
MR Jay
