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: ```auto sudo systemctl disable zkifc sudo systemctl disable zkbootrtc ``` If you’d like some help getting things working, email [support@zymbit.com](mailto:support@zymbit.com) 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? ---

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