Verify the md5sum

When you have finished downloading the LiveCD image, but before you burn the distro to a CD make sure to get the .md5sum file from the same place and verify the md5sum of the .iso against what is recorded in the file. This is to prevent errors from your download passing into the CD you burn. If the md5sum does not match, download the .iso once more.

Md5sum: Windows

Windows users should download a tool called md5summer:

  1. Download the self-extracting exe. Execute the file and it will expand 2 files in the current directory: md5summer.exe and md5summer.md5
  2. Execute md5summer.exe, respond "yes" to associate extension "md5" with md5summer program
  3. Now you can either double-click on the .md5 file and the program will check the md5 sum automatically, or from md5summer you can select as "root folder" the folder where you downloaded the .iso and .md5 files and then select "verify sums" and select the .md5 file you want to check.

Md5sum: Linux

Linux users need to open up a console/terminal and cd into the directory they have the .iso and md5sum files. They next need to issue this command:

  • md5sum -c filename.md5sum

Be sure to replace filename with the actual filename.

Md5sum: Mac

Mac users need to open up a console/terminal and cd into the directory they have the .iso and md5sum files. They next need to issue this command:

  • md5 -c filename.md5sum

Be sure to replace filename with the actual filename.
