Bug 831242

I have just experienced this on a server I am upgrading. I found a symlink in /usr/bin called 'java' pointing at /etc/alternatives/java. Deleting the symlink corrected the error and the upgrade is now proceeding.

HTH  :)

Run the command (from /usr): find . -type l | grep etc

...to check for symlinks going to /etc.

Thanks Gary,

I have checked for symlink as you suggested and unlinked the ones I saw but the script /usr merge script still fails. Any other suggestions?

Thanks

Hi Ben,

I would check for NFS/CIFS mounts that might reference that directory and run the find command I mentioned in 'Comment 2' with a pipe through "more". I think you will need to check every symlink to ensure one is not going somewhere else.

Regards

I've done the above search with the following results (doesn't look like any symlinks going to etc) and as far as I know I have no NFS/CIFS mounts for that directory eiter (just running Samba here). How do I proceed to fix this or get around it...or worst case back out what preupgrade has already done? I was able to reboot into the "old" FC16 setup manually and its working fine so I'm guessing remove the entries in the grub.conf files maybe but some direction there and what else to clean up would help if we can't resolve this.

The following find run from /usr will locate symlinks to /etc that you need to remove:

cd /usr
find ./ -mount  -lname /etc/\*

Upgraded another server in the week and I can confirm:

find ./ -mount  -lname /etc/\* -delete

sorts the problem.

I would NOT advise anyone randomly perform these commands. It's a great way to break your OS. However, all of the comments appear to aim roughly into the ballpark. I don't mean to be negative. Here is a method which can pin-point "your" issue when receiving this error, as there seems to be a few.

The idea is to use dracut as a simulation & then read the logs when it fails in the same way the script does from the installation dvd. This process will not damage your image. You're expecting it to fail.

1) sudo yum update dracut
2) sudo dracut --force --add convertfs
3) uname -r
4) sudo init 6 ### Reboot & select kernel (grub)from step 3
5) sudo dmesg|grep -i dracut

The last line should say something like "failed for some reason". Just above, it should say what the issue is.

What stopped mine was a dead simlink /usr/lib/dbus-1.

6) Find the file & delete it. In the dracut log it describes the file path as /sysroot/path/to/file. Be aware of that when deleting your file. :-)

7) Upgrade Fedora 16 to 17 from the DVD as suggested by the Fedora people. Here is a read if you still want to use Yum.

8) Enjoy!

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
