Problem with repositories in a freshly installed Ubuntu Karmic

[calsaverini]

I have a freshly installed Ubuntu Karmic 32 bits installed in an old machine (Pentium 4 512 Mb RAM) and I'm having a severe problem with apt-get.

No matter what repository I choose, I can't update the repository files. I get the following error during a
apt-get update:



Hit http://br.archive.ubuntu.com karmic-updates/universe Sources
Hit http://br.archive.ubuntu.com karmic-updates/multiverse Packages

bzip2: Data integrity error when decompressing.
Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

W: Failed while searching http://br.archive.ubuntu.com/ubuntu/dists/karmic/universe/binary-i386/Packages.bz2 Sub-process /bin/bzip2 returned an error code (2)
I have another computer in the same network that is perfectly able do download those files and update it's package database.

Also, when I try to install any package with apt-get I get a "incorrect hash sum":


E: Failed retrieving http://br.archive.ubuntu.com/ubuntu/pool/main/v/vim/vim-runtime_7.2.245-2ubuntu2_all.deb: incorrect Hash Sum

Again: I have a computer in the same network that can install any package normally, so it's not a local network problem.

Does anyone have any clue in what can be happening? I tried many different repositories.

I also had a problem installing Grub in this machine (had to resort to LILO, cause Grub wouldn't install). Can this be a hardware problem?

Tested my memory with the memtest and my harddrive with e2fsck -c. Apparently not a hardware or network problem. I thought it should be a hardware problem but I'm not sure anymore.

To simplify the error messages I kept only the main repository. This is my current sources.list:



## See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
deb http://archive.linux.duke.edu/ubuntu/ karmic main
# CDROMs are managed through the apt-cdrom tool.


(I've tried DOZENS of different repositories, including the main repo).

When I run
sudo apt-get update I get the following:



anapaola@tarugo:~$ sudo apt-get update

Hmmm... odd one.

Have you tried

sudo dpkg --configure -a

to see if it has gotten a bit 'confused' ?
