18.04aptwindows-subsystem-for-linux
When i tried to install PIP for python3 in Ubuntu 18.04.2 LTS
Command I used:
root@DESKTOP-0BEE3OD:/mnt/c# apt install python3-pip
E: Could not read response to hello message from hook [ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap --from-apt 2>/dev/null || true: Success
I am not able to fix this error.
Not sure if this will help, but perhaps try running sudo apt --fix-broken install Another thing that could be an issue is if there is something else like another apt install $PROGRAM running in the background, preventing access to that directory
EDIT
I think there was some sort of corruption issue with the hplip package. Purging then reinstalling seemed to fix the issue for OP
sudo apt purge '^hplip' and then sudo apt install hplip-data hplip-gui
In my case, I realised that even after re-installation, the issues persist. However, I realised that Hamachi's LogMeIn client was not in offline mode, which caused its Ethernet connection to interfere with Ubuntu's internet connection (but not on Windows OS). This is why when I pinged google.com it returned PING google.com(2404:6800:4003:c03::8a (2404:6800:4003:c03::8a)) 56 data bytes and stopped. The steps that @Kulfy took to help troubleshoot pointed me in the right direction, which made me realise that there was an additional Ethernet connection running.
In the future, if anyone still faces issue with their internet connection, even after reinstalling, please check that you do not have any antivirus software or other servers running at the same time, which may interfere with your Ubuntu's internet connection.
Go to Control Panel→Network and Internet→Network Connections on Windows to check whether you have additional servers running. Disable them (if found) and retry.

I had the same problem and found an answer here: Broken APT on WSL 18.04
Just like in the link I would delete the apt hook first to get apt up and running again:
Seems like Snapcraft is the problem here because it is depending on python. I tried to update pip
python3 -m pip install --upgrade pipand this seemed to mess everything up and I couldn't install any python packages anymore. So I deleted python3 and then the error occured.Note to self: Do use apt when upgrading pip. (At least on ubuntu or simillar distros)
