bad checksum

Hi All,
I have downloaded the iso twice, burned them successfully, then checked the integrity of the disk before I installed. Both times I got the message that "Checksum failed twice." Before I throw the disks out just want to make sure that means the disk is bad.
Thanks.

Hi,

It could be a bug... the verifier using some hardcoded md5sum from the Ubuntu Live CD... If you've checked the checksum yourself, I'd say the CD is fine. I'll look into that and make sure this won't happen again for the next releases.

Excuse my ignorance, but how do you check the integrity using Checksum? After learning that, I want to learn how to use bit torrent.

in a terminal: md5sum LinuxMint-2.0.iso
the result should be: f56a393d8eb304a0647ec3b2fde8d207

I realize this is Linus 101, but in terminal do you just type in md5sum LinuxMint-2.0.iso?

well... provided you're in the right directory... :)

if you're not used to the terminal here are some useful commands:

- "pwd" shows you in which directory you are.
- "ls" shows you the directories (in blue) and the files from the directory you're in.
- "cd somedirectory" makes you go in that somedirectory..

When you get to the stage where ls shows you the file for the ISO.. you can call md5sum on it..

That worked, thanks. I'm learning; slowly, but I'm learning.

Don't rely on the CD checking feature, it doesn't work well. Check the sums yourself with md5sum.

Hi there,
I also got a message about two checksums being wrong, but I ignored it and installed Linux Mint 2 anyway.
I can only admit that this a great distro. I have been testing it intensively for the last two days. I works fine.
