Red Hat Bugzilla – Bug 443291
ISO image via NFS, got "Missing ISO 9660 image" and failed to install
Last modified: 2013-01-09 23:40:25 EST
Description of problem:
During installation from ISO image via NFS, after setting boot loader, got a
message "Missing ISO 9660 image", and buttons "Exit" and "Retry".
Pressing "Exit", installation was aborted and reboot automatically.
Pressing "Retry", got same message again.
Version-Release number of selected component (if applicable):
Fedora 9 Preview release
Steps to Reproduce:
1.boot installer with boot.img or vmlinuz and initrd.img from grub
2.chose NFS install
3.put a ISO image, Fedora-9-Preview-i386-DVD.iso on the NFS server
4.select NFS server and directory that contains ISO image
5.go through installation to boot loader settings
got a message "Missing ISO 9660 image"
proceed to package selection screen
Instead of ISO image + NFS installation, installation from a NFS directory on
which loopback mounted ISO image in the NFS server was successful.

sceenshot when that message was pop-up
Instead of DVD-image, CD-image + NFS installation is successful.
I get the same bug when installing with the DVD ISO image on my hard drive as
Please attach /tmp/anaconda.log to this bug report.

We are completely unable to reproduce this problem using both the boot method
you describe as well as booting from network and booting from CD media.
No, this dose not occur with CD media. Only occur with boot.img and
DVD-ISO-image on NFS.
Do you put CD-ISO-images on the same directory where DVD-ISO-image is on?
If so, this dose not occur. I tested that condition just now.
This is a bug that anaconda try to loop mount Fedora-9-Preview-i386-disc1.iso
even installing from DVD-image.
In the image.py, findIsoImages() reads file .discinfo to get discNum, but in the
DVD image,discNum is "ALL" not "1". Anaconda dose not treat this case properly.
This is why anaconda can't find DVD image, I think.
I hexedit Fedora-9-Preview-i386-DVD.iso and change "ALL" to "1" in .discinfo.
Then, installation was finished successll.
ALL should be getting replaced with the list of discs at compose time I thought

Ugh this again? I could have sworn we deemed switching "all" to "1" to not be
necessary anymore. *sigh*
Mr. Morioka - How exactly did you change "ALL" to "1"? I have tried
"1<space><space>" and "1<new line><space>" and I still get the same error. Did
you somehow make the .discinfo file two bytes shorter? (I am trying to install
my system from hard disk, to confirm that this is the same problem as you are
having with NFS installation.)
I tried "1<new line><new line>". But I don't know why "1<new line><space>" you
tried did not work.
Here is hexdump:

Thanks. I hexedited my ...-DVD.iso file to look exactly like yours in comment
#15, but the hard disk installation continued to fail with "Missing ISO 9660
Image". There must be some other difference between the two installation types
that is causing me a problem. Another difference is that I am not allowing
Anaconda to format my /boot or root partitions during these tests - I like
having a system to come back to after the installation fails. I can attach my
anaconda.log if anyone is interested.
I have confirmed that the hexedited -DVD.iso file permits me to get past the
"Missing ISO 9660 Image" message for an NFS installation, although I didn't use
PXE and kickstart as I did previously.
Applied Jesse's patch for this

Using Anaconda 220.127.116.11:
1) Faked a netinstall from a snapshot DVD build of rawhide (askmethod mode).
Select NFS point to NFS mount point without specifying the ISO directly (in this
case Fedora-rawhide-i386-DVD.iso) Anaconda successfully installs and finds the
Cannot reproduce, seems fixed to me.
Is it possible to test a hard disk installation, since bug 443580 was closed as
a duplicate of this one? As I noted in comment #16, the workaround for the NFS
installation didn't work for the hard disk installation.
I'm testing this with HD installation.. either I'm doing it wrong or it's still
There are messages in anaconda.log that show the ISO being found and mounted
successfully, so I'm almost positive this isn't operator error.
Iso via hdd may be a different problem. I'm more concerned about iso via nfs
I confirmed that nfs iso with disc1+ works. Closing this bug, re-open hdd iso
if that's still a problem.
