Webmin Test Zone Transfer reports /usr/bin/dig: couldn’t get address for ”: not found

When testing a zone transfer in Webmin’s BIND Test Zone Transfer function, you might end up with the following output:

Testing transfer of slave zone from ..
.. from : Failed : /usr/bin/dig: couldn't get address for '': not found
.. from : Failed : /usr/bin/dig: couldn't get address for '': not found

Solution

Go to Webmin’s website and download latest version:
https://www.webmin.com/download.html

If you had a similar issue than me, this will be the result of your upgrade:

Unpacking webmin (1.970) over (1.930)
