jigdo checksum issue

I tried to download Debian 10 using `jigdo-lite`. It gives
ERROR: Checksums do not match, image might be corrupted!
Trying again I get
jigdo-file: Output file already exists - delete it or use --force
Sounds like it's was wanting me to delete all the downloads and try again. Don't want to have to do that again for something this big.

So I tried mounting the iso file**, and saw that it had a md5 file in it so I ran
md5sum -w --quiet -c md5sum.txt   
./doc/manual/en/install.en.txt: FAILED
md5sum: WARNING: 1 computed checksum did NOT match
I tried to find this file online. Couldn't find a match with the same name. Closest things I found were
kdiff3 shows these as being different, like it's a different version/edit of the same page.

[update]I found Buster's installation-guide-amd64_20190622_all.deb file (, and extracted things and found the file by this name. Looks like the one in my Jidgo iso was missing a section this has. Although, I'm still not sure as to what to do with it.[/update]

What can I do to fix this checksum issue?... How to find the right file?, Then what do with it?, or is there some auto way to redo this part?

**or at least what I think was the iso file

Somehow this fixed it?...

What I did that seemed to have fixed this:

I mounted the *.iso file
made and cd into a new tmp directory
reran the jigdo-lite
at the prompt pointed it to the *.iso's mounted directory
let it finish
Somehow it's good now, even checked the inside and outside md5

How did this fix it? I don't think it even downloaded anything this time. (Did I just miss it doing this?)
Why didn't it offer to create a new iso based off of the old iso? (instead of telling me to delete the file and start over, it could have said to do the above, or it could have done something like that for me.)
