Error message trying to initiate mirror_slackware_current.sh

Hello. Over the years I have done the same command and have never had an issue; sh mirror-slackware-current.sh -f -a x86_64.

This time around however I am getting this error towards the end and it bombs... Ive never seen this so am unsure how to isolate or repair.
