Added: Actually, I see you are trying to access a Debian repository. That could very well be the issue. Deselect it in your sources.list and then accomplish the following.

For MergeList problems, an easy way to reset the lists is to open Software Sources (not Synaptic), untick all the repositories in Ubuntu Software and the Third Party tabs, then reselect them and Reload.

That should clear any erroneous lists and reload ones without error, assuming the error is not on that server or in your sources.list. If that doesn't clear it, post your sources.list

Thanx to drs305. I was having the same problem, only when trying to add the Backtrack 4 packages. I was about to just do a clean install but your advice works well.

So... what do you do if you're trying to include sources from other, compatible distributions?

I've passed that apt limit, gone into /etc/apt/apt.conf.d/debconf70 to add a line of code that sets the default to 2x and 4x that limit, and... well, apt doesn't recognize the difference.

Here's the code I added at the end:

APT::Cache-Limit “201326592″;

to this code in that file:

// Pre-configure all packages with debconf before they are installed.
// If you don't like it, comment it out.
DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt || true";};

So, is there somewhere else that I need to change things?
