To solve this error, you may get the built kernel module for Ubuntu based on it’s distribution in their repository. The link to the repository would be as following:

http://beta.r1soft.com/modules/

Now, if you are using Ubuntu 20.04, then the module would be available under the folder: Ubuntu_2004_x64

In my case, it was Ubuntu 20.04. Next stop, is to find the kernel version. You may get it from the following command:

root@hisab:~# uname -a
Linux hisab.skincafe.co 5.4.0-128-generic #144-Ubuntu SMP Tue Sep 20 11:00:04 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
root@hisab:~#

Kernel number to note in our case, would be ‘5.4.0-128’. Now search for this inside the link:

http://beta.r1soft.com/modules/Ubuntu_2004_x64/

You should find a match, like for my case it was the following link:

http://beta.r1soft.com/modules/Ubuntu_2004_x64/hcpdriver-cki-5.4.0-128-generic.209.ko

Next stop, is to go to the r1soft module folder and load the module. You may do so like the following:

cd /lib/modules/r1soft
wget http://beta.r1soft.com/modules/Ubuntu_2004_x64/hcpdriver-cki-5.4.0-128-generic.209.ko

Now, all you need, is to restart r1soft. Remember to stop and star the agent instead of direct restart.

service cdp-agent stop
service cdp-agent start

This should be able to load the HCP module now. You may verify this by typing:

root@hisab:~# hcp --list
