[v3.0.25] Parameter -x does not wait for manual DNS configuration

[tickytacky]

Hi,

we try to install BBB current version on a local server (not reachable from the internet) with option -x to be able to do a manual DNS challange.
But the script ends up with the following error (each time we try): "An unexpected error occurred: EOFError"

Please deploy a DNS TXT record under the name:

_acme-challenge.<servername>.

with the following value:

<key>

Before continuing, verify the TXT record has been deployed. Depending on the DNS
provider, this may take some time, from a few seconds to multiple minutes. You can
check if it has finished deploying with aid of online tools, such as the Google
Admin Toolbox: https://toolbox.googleapps.com/apps/dig/#TXT/_acme-challenge.ubuntu05.splend-it.de.
Look for one or more bolded line(s) below the line ';ANSWER'. It should show the
value(s) you've just added.

So this error occurs BEFORE we can press Enter. It seems the script is not waiting for users input at this point and throws the Error right away.
