Librem 5 and Crowdsec

I am thinking to install the Crowdsec app onto my Librem 5.
Has anyone done a Crowdsec install and if so what Bouncer is good to use.
Thanks for any info.

Tried to install Crowdsec, but failed. I think PureOs is not supported.
Got the response below.

This usually happens if your operating system is not supported by, or this script’s OS detection failed.
You can find a list of supported OSes and distributions on our website:

Ay, PureOS may not be recognized as a distro to add a repo, but the bigger problem to me seems to be that lists aarch64 (as in, compatible with L5 architecture) only for rpm packages, not dep. Contact Crowdsec to hear if they would be willing to update and include PureOS with aarch64. Of course, you could try using and make from source.

Edit: for anyone interested, intro to Crowdsec: (“CrowdSec is not a SIEM, storing your logs (neither locally nor remotely). Your data are analyzed locally and forgotten.
Signals sent to the curation platform are limited to the very strict minimum: IP, Scenario, Timestamp. They are only used to allow the system to spot new rogue IPs, and rule out false positives or poisoning attempts.”). Also:

Thank you. I dont have the skill to install from source.
After further investigation, I determined I cannot afford the charges, even if Crowdsec was configured for PureOS as a deb install.
So now I am trying to figure out how to remove what I installed.
I found the below so I am going to try
apt-get remove --purge crowdsec

Well, I figured this out on my own. Something is up with the installation/removal process. You cannot do an “apt remove crowdsec” since it left files in place which I think broke this.
The result of the above is that I needed to manually remove all crowdsec folders and files myself because apt did not do that. Once I did that, I was able to install it properly.
Advice to crowdsec team: Review your “apt remove” code to ensure that it actually removes all the crowdsec files.

In the future apt-get remove --purge XXXX can be handy as it as well removes the configuration files etc (we ensured it’s working as expected in crowdsec’s case).

apologies for the bold typing, not sure how it happened.
I did the purge, seems to have worked.
purism@pureos:~$ sudo apt-get remove --purge crowdsec
