update-manager becomes unresponsive because it cannot download ReleaseAnnouncement (needs sensible timeout)

[robotpoet]

I wanted to upgrade from Edgy to Feisty. I press the "upgrade" button. Then nothing happens and the program is unresponsive.

I am not familiar with python but I tried some debugging. It seems that the problem is that the program is unable to download 'http://archive.ubuntu.com/ubuntu/dists/feisty/main/dist-upgrader-all/current/ReleaseAnnouncement'. Here is where it 'hangs':

> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(52)showReleaseNotes()
-> gtk.main_iteration()
(Pdb)
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(51)showReleaseNotes()
-> while gtk.events_pending():
(Pdb)
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(52)showReleaseNotes()
-> gtk.main_iteration()
(Pdb) s
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(51)showReleaseNotes()
-> while gtk.events_pending():
(Pdb) s
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(52)showReleaseNotes()
-> gtk.main_iteration()
(Pdb) list
 47 if self.new_dist.releaseNotesURI != None:
 48 uri = self.new_dist.releaseNotesURI
 49 self.window_main.set_sensitive(False)
 50 self.window_main.window.set_cursor(gtk.gdk.Cursor(gtk.gdk.WATCH))
 51 while gtk.events_pending():
 52 -> gtk.main_iteration()
 53
 54 # download/display the release notes
 55 # FIXME: add some progress reporting here
 56 res = gtk.RESPONSE_CANCEL
 57 try:
(Pdb) uri
'http://archive.ubuntu.com/ubuntu/dists/feisty/main/dist-upgrader-all/current/ReleaseAnnouncement'
(Pdb) s
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(51)showReleaseNotes()
-> while gtk.events_pending():
(Pdb)
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(52)showReleaseNotes()
-> gtk.main_iteration()
(Pdb)
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(51)showReleaseNotes()
-> while gtk.events_pending():
(Pdb)
> /usr/lib/python2.4/site-packages/UpdateManager/DistUpgradeFetcher.py(52)showReleaseNotes()
-> gtk.main_iteration()

I can't open "http://archive.ubuntu.com/ubuntu/dists/feisty/main/dist-upgrader-all/current/ReleaseAnnouncement" in Firefox either.

My sources.list is set to a local mirror, so it is not good that I can't upgrade because archive.ubuntu.com is down or overloaded (since everyone is trying to upgrade at the same time I assume).

Thanks for your bugreport.

This looks like a tranisent error in the archive. Can you please try again a bit later?

thanks,

I found the error. It appeared to be Firestarter that was blocking the connection to archive.ubuntu.com when "Block traffic from reserved addresses on public interfaces" was set (which seems like a bug to me - it doesn't happen in Feisty though). I tried several times so set and unset that setting and it was clearly related to being able to connect to the ubuntu server or not.

When I had found that out and unmarked that setting in Firestarter, update-manager was able to download the ReleaseAnnouncements file and the upgrade could start.
