I am trying to install zlib1gdev on windows linux subsystem. I have already done a dpkg --configure plus a update and upgrade. Hence, unfortunately first comment is no good.
and I get the error
sudo apt-get install -f zlib1g-dev
Reading package lists... Done

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.
zlib1g-dev : Depends: libc6-dev but it is not going to be installed or
libc-dev
E: Unable to correct problems, you have held broken packages.
so if I try to compare sources
sudo apt-cache policy libc6-dev libc6 libc-dev libc
libc6-dev:

So to install libc6-dev then I need to downgrade libc6 but being as its the fundamental part of a system I get the warning
You are about to do something potentially harmful
To continue type in the phrase ‘Yes, do as I say!’

I am heading down the correct path and I should just downgrade libc6 or is there another way to solve this install problem.
