Bug 957364

I've tried this with fedup-0.7.3-4.fc18.noarch and no traceback appeared. Just error message.
This is caused by upgrading to unreleased version of fedora. Boot images will be available after final release. For now you can use --instrepo 
According to fedup manual: 
       --instrepo REPOID
           Get upgrader boot images from the repo named REPOID. The repo must
           contain a valid .treeinfo file which points to the location of
           usable kernel and upgrade images.

           By default, fedup will ask https://mirrors.fedoraproject.org/ for
           the installable tree for the given --networkVERSION. The actual
           filename requested is:

           /metalink?repo=fedora-install-$releasever&arch=$basearch

           where $basearch is the system’s arch (i386, x86_64, etc.) and
           $releasever is the VERSION given with the --network option.

               Note
               You should only need to use this option if you’re testing fedup
               before the release is public.

Newest instrepo is available here - http://alt.fedoraproject.org/pub/fedora/linux/development/19/x86_64/os/

Great, thanks for confirming the URL for the pre-release repo! I've written a short post about upgrade to v19 here: http://alensiljak.blogspot.co.at/2013/04/upgrading-fedora-18-19-with-fedup.html

This will also happen if you run fedup before the new release has made it to your local mirror(s). The error looks like this:

  Downloading failed: couldn't get boot images:
  curl#22 - "The requested URL returned error: 404 Not Found"

Or:

  Error: can't get boot images.
  The installation repo isn't available.
  You need to specify one with --instrepo.

The solution is, basically, to wait and try again.

The error message could probably be clarified, e.g.:
  
  Error: can't get boot images.
  The requested release might not be available yet. Try again later.

As mentioned in the man page, --instrepo should only be needed by people testing fedup before the release is public, so we probably don't need to suggest it here.

Re comment 5, a note of clarification about bug 980818,  just in case marking it as a dupe leads to an important difference being missed. While it's describing the same problem, it's with the production repo, so it does need the clarified message.

Yes, both cases need the clarified message.

You could make the argument that --instrepo should have a different error message, like:

  Error: can't get boot images.
  Please check the --instrepo URL to make sure .treeinfo or .treeinfo.signed
  exists, contains the proper boot images, and that the boot images are readable.

but since --instrepo is for Testers Only, we can assume that anyone who uses it is an expert, and they should know that "Error: can't get boot images." means ".treeinfo or vmlinuz or upgrade.img is missing or unreadable". So I'm not going to bother adding extra code for that.

This commit should clarify the error message:

It'll be in fedup-0.8.0.

fedup-0.8.0-3.fc18.noarch failed to upgrade my Fedora 18 machine to Fedora 19.

I used this command: fedup -v --debuglog /root/fedup_f18.log --reboot --network 19

Repo files are the default ones from installation:

fedora.repo:
[fedora]
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch

I'm attaching the log file fedup_f18.log.badrepo.

Workaround was to add inst repo parameter:
--instrepo=ftp://ftp.linux.cz/pub/linux/fedora/linux/releases/1
9/Fedora/i386/os/

Note that Fedora 19 was released months ago so it doesn't seem like mirror inconsistency.

Different problem. See bug 1040689.

fedup-0.8.0-3.fc19 has been pushed to the Fedora 19 stable repository.  If problems still persist, please make note of it in this bug report.

fedup-0.8.0-3.fc20 has been pushed to the Fedora 20 stable repository.  If problems still persist, please make note of it in this bug report.

I've just tried to upgrade FC18 to FC19 or FC20 and I get the error about no more mirrors with fedup-0.8.0-3.fc18.noarch

To get up upgrade to work using fedup, I had to run this command:

$ fedup --network 19 --instrepo=http://fedora.mirror.nexicom.net/linux/releases/19/Fedora/x86_64/os

Once I did that, the upgrade worked well.
