ananconda read file data: Input/output error
Last modified: 2008-08-02 19:40:37 EDT
Description of problem:
Installation fails in anaconda with following error:
Running anaconda 18.104.22.168, the Fedora system installer - please wait ...
/usr/bin/python: error while loading shared libraries: /lib64/libc.so.6: cannot
read file data: Input/output error
install exited abnormally [1/1]
Version-Release number of selected component (if applicable):
Fedora 9 alpha and anaconda 22.214.171.124
It happens every time on this computer but is system dependent. The same DVD
behaves differently in another system (with a different version of Pioneer DVD
Steps to Reproduce:
1. insert x86_64 F9 alpha DVD in Pioneer DVR109 drive and boot
2. select install or upgrade exisiting linux (in graphical mode)
anaconda crashes -- see description of problem
The linux installation should proceed correctly.
This computer system has had a history of problems starting with FC6 and
associated with the DVD drive (a Pioneer DVR109). FC5 installed fine. FC6 would
install but it seemed to think the DVD drive was a hard disk. FC7 and F8 would
not install. I have had to use a network install to get F8 onto it. The problems
seem to be getting worse with each release! I am alpha testing F9 to try and get
this problem fixed. Compare also with bug 435647.
Did you verify the media using mediacheck?

> Did you verify the media using mediacheck?
Unlike most Fedora CD/DVDs which offer the user a graphical interface (after
the driver installs) to check the media, or skip the test, this one does not.
I have tried a boot with linux mediacheck and it reported no problems with the
media (that I could see). This comment is made based on observations on a
different system to the one this bug was reported for as that system is
I am sceptical that the problem is with corrupted media as exactly the same
media in different systems behaves differently (i.e. this particular error does
not occur with another system). My presumption (possibly wrong) is that the
error lies in how the DVD is being read rather than what is on the DVD.
I would run a checksum on the iso image but don't see any available at the
The SHA1SUMS are available in the mirror iso directories. See:
You can verify the iso image easily using bittorrent. Place the image in a
known directory, then go to torrent.fedoraproject.org and start downloading the
torrent for that image (it will check the file and tell you if it is not complete).
Changing version to '9' as part of upcoming Fedora 9 GA.
