NOTE: I understand nothing whatsoever about Terminal commands and outputs.

Launching v.4.0.2 from the Terminal (Linux): no problem.

Updating in the Terminal ("Installation from Python sources") everything as per previous versions. "Install dependencies", Download package, Verify signature, Run without installing and Install with PIP: all OK.

But! No response from the Desktop Configuration File and lauching from the Terminal then gave this:

Code:

Traceback (most recent call last):

TypeError: __init__() got an unexpected keyword argument 'requote'

I then downloaded it from Sources and Binaries. After unpacking it, also here the Desktop Configuration File doesn't respond. The only way I can launch this version is by opening the Python 3 script file called run_electrum found in the unpacked directory. Which I find rather untraditional.

What's going on?
