Cannot install on Ubuntu 18.04 QDate value Error

[johnos999]

Hi,
I'm trying to install Fissure Python2_maint-3.7 on Ubuntu 18.04.6 but
I get the following QDate Error, and the install stops:

john@john-HP-Pavilion-15-Notebook-PC:~/fissure$ ./install
Traceback (most recent call last):
File "/home/john/fissure/Installer/installer", line 13, in
form_class = uic.loadUiType(fissure_directory + "/UI/install.ui")[0]

File "/usr/lib/python2.7/dist-packages/qgis/PyQt/QtCore.py", line 28, in
sip.setapi(api, 2)
ValueError: API 'QDate' has already been set to version 1

------ The install process stops at this point -----

Any ideas what could cause this?
I generally keep the software for this version of Ubuntu up to date.

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.6 LTS

Codename: bionic

Thanks,

It might have to do with other programs on your system. Let me know if you figure out which one. Could be something like this: https://stackoverflow.com/questions/42444150/sphinx-qt-valueerror-api-qdate-has-already-been-set-to-version-1
