Installation of Pi Hole fails

Software SW help

Hi,

i am trying to install pi-hole in an LXC container on my Omnia. However, the installation fails.
These are the last few lines of the output:

This is reconstructible, multiple runs of the installation script result in the same output. Pi Hole isn’t fully installed after this, lighttpd isn’t started or reconfigured. The line “Kernel update detected, if install fails reboot and try again” is meaningless, i rebooted my Omnia because of this, the only result is this line disappearing, but the install failing anyways.

The LXC container is running Debian Stretch. Any help?

OK maybe try run apt-get update and apt-get upgrade and after that run the installation again - same thing happened to me a month ago.

After that it should be OK it’s because those two items in the list with “will be installed”.

Just wondering why do you need pi-hole when knot resolver does exactly the same thing.
Take a look below. For me it works fine.

Because of the GUI and easy settings, navigation, graphs, statistics, logs etc. It’s complete and working solution. I don’t want to do everything in command line (I can do that in a work whole day, not at home).
