Good Morning dear Community,


this is my first post here.. because.. i have a problem ,-]

I need to install the "isc-dhcp-server"

Before i wanna make "apt install isc-dhcp-server" i wanna do "apt update and apt upgrade".. this fails before i come to the dhcp server..

btw. please excuse my poor english..

this is what i try >

apt update seems to be ok:
root@ilak-abas:~# apt update
Hit:1 http://dl.google.com/linux/chrome/deb stable InRelease
Hit:2 http://ftp.halifax.rwth-aachen.de/kali kali-rolling InRelease

894 packages can be upgraded. Run 'apt list --upgradable' to see them.

then i do apt upgrade: and here the problems begin

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
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
ruby-http-parser.rb : Conflicts: ruby-http-parser but 1.2.1-4 is to be installed
E: Broken packages

This is my sources.list:

# deb cdrom:[Debian GNU/Linux 2019.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20190228-17:12]/ kali-last-snapshot contrib main non-free

#deb cdrom:[Debian GNU/Linux 2019.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20190228-17:12]/ kali-last-snapshot contrib main non-free

deb http://http.kali.org/kali kali-rolling main non-free contrib
# deb-src http://http.kali.org/kali kali-rolling main non-free contrib

# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.

I hope you can help me, at least bring me a step further
