Hi! First of all, sorry for the inconvenience.

Vailyn only works with relatively new versions of Python 3 (it has been officially tested with 3.7 and 3.8, but it should work with 3.6 too).

The error you are getting probably means that they have retired the package from the Python2 repos. However, even if it would succeed, Vailyn would not run due to the major changes between Python 2 and 3.

Please, try to repeat the installation with Python 3, and report back if it works. The commands should be either pip3 or python3 -m pip.

Greetings!

Edit: above reason is correct, the makers of PyQt5 have dropped support for Python < 3.5. So, using above commands should resolve the issue.

[juushya]

Yeah, this works with python3 only. Here's how I got it running:

Install pip3

# apt install python3-pip

Install requirements (pyqt5)

root@kali:/opt/Vailyn# python3 -m pip install -r requirements.txt

Running Vailyn python3 Vailyn -h <--- works only with python3, throws a traceback with python2.x

It seems QT may not work. Here's a screenshot of a query attack (I hope this is correct config):

[VainlyStrain]

It seems like a style sheet issue. Will take a look at it.

Just a question: is the grey part in the first picture part of the issue, or is it applied to censor the IP/port?

[VainlyStrain]

should be fixed in the latest commit. Let me know if the issue persists, and I'll open the issue again :)

[juushya]

The grey part in the first pic is just a censor. The second pic shows the actual issue. I'll pull the latest version, and give this a shot. Thanks.
