IPv6 is disabled on my VPS. Installer works fine if I say 'no' to starting the containers. If I say 'yes' then it gives me an error about the ipv6 portion because it's not available on my VPS. This also halts the installer so you never get asked about anything after this point like Crowdsec. I did originally comment out the IPv6 portion of the compose file and everything worked fine, I just realized after that it never did actually finish the installer. I tried it again just to be sure and then moved onto inputting 'no'.
