Hi, can you please retest with:
http://akozumpl.fedorapeople.org/bz_dispatcher.img

And see if it fixes the problem or attach the new traceback?

Thanks.

Proposing as a F16Beta release blocker due to the following criteria ...
   "The installer must be able to successfully complete an upgrade installation from a clean, fully updated default installation (from any official install medium) of the previous stable Fedora release, either via preupgrade or by booting to the installer manually. The upgraded system must meet all release criteria "

I think you are hitting a new error, because the logs show you moved past the original point of failure. I am going to push my fix, once it gets into f16 builds (post alpha probably?) you can open the new bug.

Proposed patch:

https://www.redhat.com/archives/anaconda-devel-list/2011-August/msg00080.html.

Fixed by c3bedc8c5b1542e882824d5fb4005f6336e7822a.

For F16 this will be a part of the first post-alpha Anaconda build.

With both Fedora 16 Alpha RC1 and RC3, I get a similar but different dispatch error.

When I click the next button after selecting my Fedora 15 partition to upgrade, I get something like:

Dispatch error:cannot reschedule step 'language' from 'skipped' to 'requested'

I'm unable to save event though (doesn't like my wireless network and doesn't prompt for saving to disk) so this is from memory.

The proposed patch in Comment 14 changes both 'findinstall' (title of this bug) and 'language' to both be schedule_steps_gently().  So its my hopes this will also fix my issue.

I'll retest when updated ISO is available... but I wanted to get the phrase 'language' in comments for benefit of other users getting same  variation of error.

I'm unable to upgrade as-is.

Your bug is the same with bug 728122

Thanks for pointer that bug 728112 is what I was seeing.  I just tried RC4 with anaconda 16.14.5 and still see issue. I do not know if the comment 14 patch was ever committed.

DispatchError: Can not reschedule step 'language' from 'skipped' to 'scheduled'

It was committed but it won't make Alpha. The problems with the dispatcher exist because I made a bunch of cleanups to it during f16 development and those are errors coming back. Since the upgrade path is not considered as critical for alpha we decided not to merge the latest fixes there and make the branch stable for the basic install sooner instead.

Adding keyword 'CommonBugs' to this issue so the problem can be documented until the bug is resolved in a post-Alpha anaconda build.

Discussed in the 2011-08-26 blocker review meeting. Accepted as a Fedora 16 beta blocker as it violates the following beta release criterion [1]:

The installer must be able to successfully complete an upgrade installation from a clean, fully updated default installation (from any official install medium) of the previous stable Fedora release, either via preupgrade or by booting to the installer manually. The upgraded system must meet all release criteria

Hongqing, can you please confirm the status of this bug with Beta TC1? Thanks!

In my testing, this bug is fixed in TC2, and you run into https://bugzilla.redhat.com/show_bug.cgi?id=735730 later in install. Moving to VERIFIED for now, but it should probably be CLOSED. Hongqing, if you could confirm that would be great.
