DNS, Lightppd

Presently trying to get Pihole up on my TS451+. Lots, and lots of issues. However, I am unable to get FTL or DNS.

Using ubunto 18.04 in containers storage

Errors i get on install are: no default index.html
DNS not running.
Manually restarting lighttpd - I can get admin console
-no dns
-no ftl and the wheel jsut spins
stopping/restarting lighttpd -errors out Unable to bind to port 80 or any port for that matter
