Adding the missing PTR record should resolve the issue and the upgrade should be successful.
Steps:
host $( iface-ip eth0 ) # if this returns a single line, but /usr/bin/dig +noall +answer -x $( iface-ip eth0 ) # this contains no ANSWER section, and /usr/bin/dig +noall +answer +noedns -x $( iface-ip eth0 ) # this also returns the corrrect line, then EDNS is probably broken.
