How to uninstall zimkey software on unbuntu 22.04

How do I safely remove the zimkey software from my ubuntu 22.04 machine. The install failed and I don’t really want to invest the time to get it working at the moment.

@George - You can simply disable the following two services if you don’t want anything to run on bootup:

sudo systemctl disable zkifc
sudo systemctl disable zkbootrtc

If you’d like some help getting things working, email and we’ll help you.

Thanks for the quick response Bob. I have a personal project where I am using OpenVpn and several pis on my home network. I bought the zymkey4 hoping it would speed up the TLS/SSL. I want to get everything up and running and will then come back to this. I did a systemctl status on the services and they were both running. The blue diode never came on after reboot and the python scripts failed. Any other hints on what I might check before I give up?

Here is the error from crypto_test, the util test has similar results:

~/Zimkey$ python3
Exception ignored in: <function Zymkey.del at 0xffff91bd1cf0>
Traceback (most recent call last):

Signing data…Traceback (most recent call last):
File “/home/george/Zimkey/”, line 10, in
signature = zymkey.client.sign(secret_message)
AttributeError: ‘NoneType’ object has no attribute ‘sign’

Just a quick post that running the install script again fixed the problem.

Wanted to post a public thank you to Bob. World class tech support!!
