I stopped using Linux for a while, but recently began a computer science course in college and decided to install Ubuntu 11.04 into VMWare.
I needed to download an IDE. I type:
user@ubuntu:~$ sudo apt-get install geany
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_natty_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
I remembered about the "clean", "clean all", and "update" flags. So I tried them. I didn't copy everything, but there were more errors higher up in the terminal.
user@ubuntu:~$ sudo apt-get clean
user@ubuntu:~$ sudo apt-get update

E: Some index files failed to download. They have been ignored, or old ones used instead.
So, I thought I could delete the aptitude lists and it would fix it. So I did.

And then, tried to update again.
Same errors.
Can someone help me, please?
