CrowdSec "can't install on Proxmox" -- LXC specific docs

[cwmoriarty]

When running on SSH shell works-as-intended: ⚠️ Can't Install on Proxmox

Maybe the script and/or documentation should let the user know where to run that command (any LXC)

[tteck]

It does

To Install CrowdSec, ⚠️ run the command below in the LXC console.

Ahh, missed that! Great.

Maybe the error could say something similar too?
