Expected Behaviour:
- Web interface, of course.
-
sudo pihole -r(re?) installs lighttpd. -
sudo pihole -upwould fix or update the system. -
sudo apt-get remove lighttpdwould remove it. -
sudo apt-get install lighttpdwould install it.
Actual Behaviour:
- No web interface!
-
sudo pihole -rselecting repair option returns this:

and then does not actually install lighttpd. I get to the "installing packages" console screen, hangs at 0% for a few seconds, and kicks back to console, no fix.
- The command returns much the same as the -r option, adding this at the top:
[i] Checking for updates...
[i] Pi-hole Core: up to date
[i] Web Interface: up to date
[i] FTL: update available
[i] FTL out of date, it will be updated by the installer.
And at the bottom:
Unable to complete update, please contact Pi-hole support
And here I am! 
- The console command returns this:
Package 'lighttpd' is not installed, so not removed
-
sudo apt-get install lighttpdreturns this:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Looking at this error message again, the libssl1.1 breaks lighttpd part is concerning, and may be the source of my woes. However, I have not yet looked into this, and for all I know it's a dependency of the nextcloud installation.
Other info:
I am running the pi-hole dual-style with LAN and VPN, inside a nextcloudpi system image. Absolutely everything is working like a charm, except for the lighttpd service and web interface, which was working in the past, along with everything else. From the start I changed the port in /etc/lighttpd/lighttpd.conf to be 8087, my preferred alternative, since nextcloudpi is already using 80. I recently also copied the contents over to /etc/lighttpd/external.conf, and commented out the last lines, as I read somewhere that it may help. It did not.
Result of sudo service lighttpd status -l

Before I tinkered around and got the service into this state, the previous command returned a result that the service was "masked". I issued commands to unmask it, and now this is the result. No changes after several reboots.
Hopefully this isn't too much info, but as a semi-noobie, this problem has really thrown me for a loop. I love this pi-hole stuff, and if I can get the web interface working again without a full pi-hole re-install, that'd be great! Thanks in advance.

Edit because I figured out how to format the code bits a little nicer, and I figured maybe the weird errors from trying to install lighttpd manually might shed some light on the situation.
