There is nothing we can do. It’s not able to retrieve the key from the server. Probably a firewall is blocking that request?

To get around this you can edit the script code fogproject/lib/common/functions.sh, jump to line 601 and comment that so it looks like this.

...
            esac
            ;;
    esac
#    errorStat $?
    dots "Preparing Package Manager"
    $packmanUpdate >>$workingdir/error_logs/fog_error_${version}.log 2>&1
...

Now rerun the installer and you should get past the repo stuff.

@Sebastian-Roth Weird I figured that was the issue, so I whitelisted the machine on my firewall just to test but still didn’t work and there’s nothin in the firewall logs to suggest that it’s blocking anything, it’s a strange one…
Will give your suggestion a go now.

@Kagashe Editing the script solved it, thanks Sebastian.
