You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libpython3.6 : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
 libpython3.6-dev : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
 libpython3.6-stdlib : Depends: libpython3.6-minimal (= 3.6.5-5~16.04.york0) but 3.6.5-5~16.04.york1 is installed
 python3.6 : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
E: Unmet dependencies. Try using -f.

I had installed using PPA JonathanF in Ubuntu 16.04, and it was working fine until I encountered this issue today.

TI tried and got the below error:

$ sudo apt-get upgrade -f

This answer worked for me =)

sudo dpkg --install --force all /var/cache/apt/archives/libpython3.6-stdlib_3.6.5-5~16.04.york1_amd64.deb

From: https://stackoverflow.com/a/50408787/1503549

NB: Remember to perform the following afterwards:

sudo apt install -f

Replace "apt" with "apt-get"/"aptitude", or whatever apt-derivative you're using.

Looks like your packages are partially out of date. Updating the package list and then upgrading installed packages with available upgrades should fix the broken dependencies:

sudo apt-get update
sudo apt-get upgrade -f

If not, could you please edit your question to include the complete, verbatim output of the above commands? Thanks.

You might have python 3.6 being installed from multiple places which is causing the issue (http://ppa.launchpad.net/jonathonf/python-3.6/ubuntu for example).

If this is the case, you need to comment or remove it from /etc/apt/sources, do an apt update, then try apt-get -f install again.
