[SOLVED] Downloaded Ubuntu 12.04.2 from Linuxiso.org. Md5sum mismatch

gcinglis · 03-04-2013, 09:24 PM

Hello my name is Gordon. My attempt to download an md5sum verified copy from more than one mirror produces an identical md5sum result between mirrors BUT differs from the linuxiso.org supplied md5sum.

1. Do they update the isos without changing the md5sum.?

2. Is it possible an external source is uploading an altered and unrelyable copy to the indexed original file provided?

Why not download it from ubuntu.com ?

Congratulations. You did one of the first steps. Does your md5 number match what is posted at ubuntu or did you test the disk with ubuntu tool? At one time, downloads all had to be checked. I haven't done that in a while but you could have any part of the data path failing. From the source iso to modem to memory to hard drive and such.

Would downloading from another site be like taking a risk?
(the integrity could be compromised somehow)?

Thankyou snowpine and jefro for providing me an obvious solution.

I took your advice and downloaded from Ubuntu direct and found that even then, the download came from a mirror site giving me the same md5sum result as those downloaded from the linuxiso.org mirrors.

I installed but now have a different problem I will post to forum.
