I have installed Ubuntu 12.04 in the morning and since than I'm struggling to do a simple update. I have troubles with apt-get. I have tried every solution i found out on the Internet, but didn't work. Here is the error i encounter when I try to
sudo apt-get update E: Could not open file /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_precise- updates_multiverse_binary-i386_Packages.IndexDiff - open (2: No such file or directory)
The whole thing started because when I tried to do the updates I received this error :"Requires installation of untrusted packages" and i found a link, I changed settings to accept source code and all other stuff and it still didn't work.
Then i went into another link and i did something like this:
sudo apt-get clean cd var/lib/apt sudo mv lists lists.old sudo mkdir -p lists/partial sudo apt-get clean sudo apt-get update
and after that I had trouble with some keys and I found the solution, but now I have this error.
sudo apt-get updatein a console and write your password? Is this correct? Can you provide details as to what you've tried (links please!)
