403 - Forbidden, unattended install

[EWouters]

Hi, I use Pi-hole with much joy.

I am trying to install Pi-hole now in unattended mode, but when it finishes I unfortunately only get "403 - Forbidden" in the browser.

I install using the following commands:

setupVars=/etc/pihole/setupVars.conf
if [ -e "${setupVars}" ]; then
  sed -i.install.bak '/PIHOLE_INTERFACE/d;/IPV4_ADDRESS/d;/IPV6_ADDRESS/d;/PIHOLE_DNS_1/d;/PIHOLE_DNS_2/d;/QUERY_LOGGING/d;/INSTALL_WEB/d;' "${setupVars}"
else
  mkdir -p /etc/pihole
  touch "${setupVars}"
fi
{
  echo "PIHOLE_INTERFACE=eth0"
  echo "IPV4_ADDRESS=192.168.1.99"
  echo "IPV6_ADDRESS="
  echo "PIHOLE_DNS_1=8.8.8.8"
  echo "PIHOLE_DNS_2=8.8.4.4"
  echo "QUERY_LOGGING=true"
  echo "INSTALL_WEB=true"
}>> "${setupVars}"
cd /etc/pihole
wget -O basic-install.sh https://install.pi-hole.net
chmod +x basic-install.sh
./basic-install.sh --unattended

The install log shows no problems and pihole -d shows
chown: invalid group: ‘root:pihole’
which might be a problem and
::: /etc/pihole/blacklist.txt not found!
::: /etc/pihole/adlists.list not found!

My debug token is 51dn42afj0

Also if I run curl -I localhost:80/ I get

HTTP/1.1 404 Not Found
X-Pi-hole: A black hole for Internet advertisements.
Content-Type: text/html
Content-Length: 345
Date: Wed, 05 Apr 2017 06:26:15 GMT

and curl -I localhost/admin

HTTP/1.1 301 Moved Permanently
Location: http://localhost/admin/
Date: Wed, 05 Apr 2017 06:27:34 GMT
Server: lighttpd/1.4.35

while in the browser I get a 403 error.

Thanks!

Which address are you typing in your client browser when you get the 403 error? All the curl responses look correct and are giving the proper responses.

I use http://localhost/admin/, like I used in the curl command.

It is fixed after I uninstall and reinstall without --unattended, but that is not what i'd like to do.
