It's very important you copy these commands carefully, with the wrong folder paths you can do some harm to your system.

This will purge the old cache so to speak.

Code:
sudo rm /var/lib/apt/lists/* -vf

This will then update the caches again for the repos. Then procede to run updates as you normally would.

Code:
sudo apt-get update

If the error continues please post a your /etc/apt/sources.list file.

Hi katME,

The way to post an image here is to upload it to the web, get the link to it and post it here.
Easiest, as they even don't require an account, are services like:

http://www.pixhost.org/

https://imgur.com/

Of course you also can use online storage like Dropbox, if you have an account.

In general, you might want to check that the picture does not contain privacy critical information.

Hope that helps Smile
