Just applied this update to my RPi Zero W and at the very end of the update log got this error:

/srv/http/settings/system.php
awk:
cmd. line:
1:
BEGIN { printf "%.1f\n", / 1000 }

awk: cmd. line:1: ^ unterminated regexp
awk: cmd. line:1: BEGIN { printf "%.1f\n", / 1000 }
awk: cmd. line:1: ^ unexpected newline or end of string
