I have just had a go at downloading the same image  file if I run
sha1sum on the img file i get a different checksum to
b4375dc9d140e6e48e0406f96dead3601fac6c81 which is mentioned on both the
website inside the file you download with this checksum in.  Either the
site hasn't been updated with a new checksum file or there is something
wrong with the downloading.

Maybe there is something wrong with the actual image  what do other
people get for the checksum vs the given checksum

Thanks Paul, I'll try and follow the instructions, but if you get a bad image doesn't that mean   itwon't be worth it as there is something wrong with the download?
Allthe best Jon.


I have finally got the card into a card reader but I have no idea what to do next, I know it was explained to me but it lookas different....I've coppied everything into a folder attached to show you what I mean;
Unfortunatly I moved the whole contents of the folder to a folder which already had stuff on it. I expect you'll be able to easily distinguish the debian folders from the rubbish from my desktop.

......no wait forget about that. Even though I downloaded a different image which I thought would work I have just tried to open one and it says it's not a valid archive. So again I have downloaded a non valid archive...I don't really understand that stuff about checksum to be honest? how does that work?
