18.04: Cannot install texlive-full

Question

I freshly installed Ubuntu 18.04 last week, meaning I have not upgraded from 16.04, rather formatted the hard drive and installed 18.04.

I am trying to install texlive-full, but whenever I use:

sudo apt install texlive-full

this is what I get:

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.

Suggestions?

Edit: this the output of sudo apt-cache policy texlive-full:

$ sudo apt-cache policy texlive-full
texlive-full:

Solution

During chat session we discovered that OP had texlive-related package from JonathonF's PPA:

$ dpkg -l | grep york
ii libkpathsea6:amd64 2018.20180129.46472-0york1~16.04 amd64 TeX Live: path search library for TeX (runtime part

We removed this package with

sudo apt purge libkpathsea6

And then installed TeXLive

sudo apt install texlive-full

Check images in my other answer - do you have enabled all software sources? Also I recommend to switch to Main server.

[Manuel Uberti]

Switched to Main Server. Did sudo apt update. Still same error.

[Manuel Uberti]

@N0rbert also yes, I have enabled all the software sources.

[N0rbert]

Try to remove all apt-lists with sudo rm -rf /var/lib/apt/lists/* and then retry sudo apt update, sudo apt install texlive-full.

[Manuel Uberti]

Same error again.
