FYI, I found another thread that had a similar issue. It seems to be related to lightppd. I ran through the installation, this time not installing the web console or the lighttpd server, and it worked fine. Now I need to somehow get those to install.

Ideas on why they won't install?

Something going wrong in below bit of the install script trying to change ownership with a non existent user "lighttpd":

# Install base files and web interface
installPihole() {
    # Create the pihole user
    create_pihole_user

    # If the user wants to install the Web interface,
    if [[ "${INSTALL_WEB_INTERFACE}" == true ]]; then
        if [[ ! -d "${webroot}" ]]; then
            # make the Web directory if necessary
            install -d -m 0755 ${webroot}
        fi

        if [[ "${INSTALL_WEB_SERVER}" == true ]]; then
            # Set the owner and permissions
            chown ${LIGHTTPD_USER}:${LIGHTTPD_GROUP} ${webroot}
            chmod 0775 ${webroot}

Whats the OS ?

lsb_release -a

Does that lighttpd user exist ?

grep lighttpd /etc/passwd

Is lighttpd already installed ?

apt policy lighttpd

Is it running ?

sudo service lighttpd status

If running, what user is it running under:

ps -o user -C lighttpd

If no lighttpd installed, try install manually:

sudo apt install lighttpd

And run the Pi-hole install again.

I made some progress. I got lighttpd to install, by running dns remove lighttpd, and then ran pihole -r again. This time it installed it. I am now getting what looks like permission issues.

Whats the OS ? - Fedora 27 Server

Does that lighttpd user exist ?

grep lighttpd /etc/passwd
lighttpd:x:983:982:lighttpd web server:/var/www/lighttpd:/sbin/nologin

Is lighttpd already installed ? Yes, it is now.

Is it running ? No.

Here's the lastest. Like I said, I had it installed before, and it worked fine, but my server installation got borked and I had to uninstall and reinstall some stuff to get things working again.

For diagnosing, try do below:

sudo chmod 777 -R /var/log/lighttpd

Start lighttpd:

sudo service lighttpd restart

Check again:

sudo service lighttpd status

And if running, check what user its running under:

ps -o user -C lighttpd

EDIT: See below for setting proper ownership and permissions of that /var/log/lighttpd folder !

that seems to have worked. Thanks!

No user ?
Maybe need sudo (EDIT: no need for sudo if run as root user):

sudo ps -o user -C lighttpd

EDIT: not over yet, still need to set proper ownership and permissions for the /var/log/lighttpd folder

EDIT2: I wasn't paying attention, we're interested in the "lighttpd" process and not the "lighttpd.conf" file !

Try again:

ps -o user -C lighttpd

10

[root@galactica etc]# ps -o user -C lighttpd
USER
lighttpd

11

For proper ownership:

sudo chown lighttpd:lighttpd -R /var/log/lighttpd

For proper permissions:

sudo chmod 750 /var/log/lighttpd

sudo chmod 644 /var/log/lighttpd/*

Restart:

sudo service lighttpd restart

And check:

sudo service lighttpd status

12

Webinterface was working before, but permissions are changed. Still appears to be working properly.

Permissions did actually make a difference. I noticed there was another failure in systemctl.

look at the date/time.

Good point. Last night was when I was trying to figure out the whole lighttpd issue on my own.
