Major failure of software management system
 

I was trying to install the flash player and I have put something wrong into my /etc/apt/sources.list

When I type into the console "sudo apt-get install -f" I get the following message
Type '<DOCTYPE>' is not known on line 3 in source list /etc/apt/sources.list The source could not be read

If I go to the applications menu and add/remove then it tells me that I have a major failure of my software management system

Looks more like some typo or minor misconception. Which distro, and what line exactly did you add/change?

M.

Additional Info
 

I am using Ubuntu 8.10

I was trying to add medibuntu to my source list.

I have found the problem and solved it. I had a file in my /etc/apt/sources.list.d that was called medibuntu.list.

I renamed the file medibuntu.saf and my problem is fixed. I will go back and delete the file now.

Thanks for your help
