update manager crashes when there are no updates

[Jose Bernardo]

Binary package hint: update-manager

TEST CASE:
1. install hardy
2. open a terminal
3. run "sudo update-manager --dist-ugprade"
4. watch failure in the terminal window

5. install update-manager from hardy-propose
6. repeat step 3
7. verify that there is no failure this time

I am already running the Hardy beta, and decided to try updating my system to the latest version running 'kdesu "adept_manager --dist-upgrade-devel"'. After detecting there are no upgrades, update manager crashes:
Traceback (most recent call last):
  File "/tmp/kde-root/adept_managerHJMRla.tmp-extract/dist-upgrade.py", line 60, in <module>

Adept should probably not offer a upgrade if there is no new version in the meta-release file. I add a adept task.

The crash in the release-upgrader is fixed now in my bzr tree.

Accepted into hardy-proposed, please test.

[Martin Pitt (pitti)]

Although not all fixed bugs have been verified, four tests from Brian showed that update-manager is still able to upgrade from dapper and gutsy, and fixed some bugs. Due to the urgency of some bugs I have copied this to hardy-updates now.

Problem with the ubuntu mirrors?

I'm running the update as i type,
unfortunately i'll probably have a lot of work..

Whats up.

As in bug 41023 my the following lines are commented out by
the update-manager.

# deb ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper main restricted universe multiverse
# deb-src ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper main restricted universe multiverse

# deb ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper-updates main restricted universe multiverse
# deb-src ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper-updates main restricted universe multiverse

# deb ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper-backports main restricted universe multiverse
# deb-src ftp://ftp.belnet.be/mirrors/ubuntu.com/ubuntu/ dapper-backports main restricted universe multiverse

So they are just commented out, and not changed to hardy..

So for now,
the "cleaning up" step takes like for-ever.
this got me wondering

Continuing:

1.

So i tried the same with other mirrors from
https://wiki.ubuntu.com/Mirrors?highlight=%28mirrors%29

namely:
ftp://ftp.belnet.be/pub/mirror/ubuntu.com/
and
ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/ubuntu/ubuntu/

both are not recognised (unknown mirror) in the upgrade process,
so the wiki page has misleading info

2.

from there i tried:
https://launchpad.net/ubuntu/+archivemirrors
and both have differences..

(not relevant for this bug, but amusing: so i decided i should make this more clear on the wiki page / mirrors,
but for some reason is the password for launchpad which is kept by firefox,
not the right one; although i am logged in with it on launchpad, unable to change my password in launchpad, still following?:)
So i didn't change the wiki..)

3.

Some interesting errors:

[Wim (wim-bertels)]

to change in the dist-upgrade scripts

1.
A. or remove the http://archive.canonical.com/ubuntu/ mirror in the dist-upgrade process (update-manger -c -d)
B. or update this mirror (it is out-dated at this moment)

2.
A. adapt the webpage https://launchpad.net/ubuntu/+archivemirrors of the official archive mirrors (and if possible https://wiki.ubuntu.com/Mirrors),
since all the mirrors from this webpage were recognised as "UNKNOWN mirror", thus were commented out during the dist-upgrade, and no distupgrade was performed as a result.
B. or adapt the webpages http://www.ubuntu.com/getubuntu/upgrading (and if possible https://help.ubuntu.com/community/HardyUpgrades) to make sure the persons who upgrades uses a recognised mirror
C. adapt the update-scripts, so that the not recognised mirrors are recognised.
