Latest Ubuntu, python3-pyqt4 and libffi6 not available

Post by hunter_235711 » Fri May 15, 2020 6:36 pm

Hello, I'm following the instructions here to get Kerberos SDR set up on my PC running Ubuntu 20.04 LTS. However, I get the following error when I try to install all the packages.

Code: Select all

[email protected]:~$ sudo apt install python3-pip python3-pyqt4 build-essential gfortran libatlas3-base libatlas-base-dev python3-dev python3-setuptools libffi6 libffi-dev python3-tk pkg-config libfreetype6-dev php-cli wondershaper

I was able to get it working, I just modified the python code to use QT5 instead of QT4. I might put the modified code on github in case other people are interested.

Hey,

I found that problem as well. I ended up just making a new Linux build around 18.04. A install that works with Ubuntu 20.04 would be good if you could share those edits.

Hello,
interesting discussions. I have the same problem with Ubuntu 20.04. The ibffi6 and python3-pyqt4 have been updated to libffi7 and python3-pyqt5 under Ubuntu 20.04. However, that does not fix the problem (see my independent post "Kerberossdr software on Ubuntu 20.04 LTS" - just recognized your post that is addressing the same problem.
@hunter_235711 - could you please describe how you have changed the code to use QT5 (if that fixes the problem)?
Many thanks!

Yes if you can put it on Github that would be great! I assume everything is still functional after the port?

I would be interested in your github repo too. Just changing the references in the python code to PyQt5 didn't do anything for me.
