I am having trouble installing crowdsec on an ipv6 only host. I am using the packagecloud apt repository to install on a debian 11 server. The installation starts but I get an error when it tries to register to the CAPI: “panic: runtime error: slice bounds out of range [:32] with length 0”.
This is followed by a traceback (which I am unable to include in this post) before the install fails.
Any ideas or pointers?
Keith

Hello,
This issue will be fixed in the next release.
In the meantime, run `dbus-uuidgen --ensure`, and retry the installation, it should work.

Perfect. Worked first time. Thank you.
