Bug Description

TEST CASE:
This bug is only triggered on e.g. LDAP systems. So we need a regression test to ensure that nothing breaks with it from the
SRU testers:
1. enabled karmic-proposed
2. setup a proxy
3. run update-manager -d
4. upgrade to lucid
5. verify that nothing breaks

- If you have a setup with external authentication, please test the fix in luicd-proposed.
- If you do not have a setup with external authentication, add a non-existent user as 1rst member of the admin group. The /etc/group file must have an entry looking like:
admin:x:111:nonexistentuser,adminuser

**WARNING** do not remove your admin user name from the admin group.

=====
Binary package hint: update-manager

I tried to upgrade my laptop (Acer WLMi5003), running Ubuntu 9.10 to Ubuntu 10.10. I tried to this two times but both times upgrade fails with following information:
___________________________________________________________________
Could not install the upgrades

The upgrade is now aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a).

Please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.
E:Sub-process /usr/bin/dpkg returned an error code (1), E:Sub-process /usr/bin/dpkg returned an error code (1)
____________________________________________________________________

All files in the above mentioned directory are in the attached file, upgradeLogs.tar.bz2

Note1: My upgrade path is: 8.10-->9.04-->9.10-->10.10LTS

Ok, although bit hard as the laptop doesnt boot normally. I am running now in emergency console. When I give the command I can see the following in screen

+ set -e
+ test -f /etc/apt/trusted.gpg
+ dpkg --compare-versions 0.7.5.3ubuntu7 lt-nl 0.7.5.3ubuntu2
+ set_apt_proxy_from_gconf
+ cut -d, f1
+ cut -d, f4
+ getent group admin
+ admin_user=÷

÷ [ -x /usr/bin/sudo ]
÷ [ -z ]
÷ [ -x /usr/bin/gconftool ]
÷ sudo -u + gconftool --get /system/http_proxy/use_http_proxy
+ use=

Thats it. Br Pekka

I'm really sorry about this bad experience. I have one more request. Could you please provide the output of:
$ getent group admin

The fix is trivial but I'd like to know why the command returns a non-existent user.
I'm turning on the privacy flag.
Thanks in advance.

Ok. Getent returns
admin:x:115:+

That reminds me that I have ldap in use and all user exept root should come from server. So far ldap installation has worked i.e. in older distros and upgrades, no changes here by me specifally for this 9.10 --> 10.04 upgrade.

So farthe fix is Ok.

- I took the karmic backup dump (from which the initial upgrade to lucid failed) and rolled back to that
- I added karmic-proposed to updates
- I selected python-apt, update-manager-core and update-manager from karmic-proposed
- I updated the above
- then I selected upgrade to lucid, no problems related to apt / update-manager any more

More testing info or testing needed by me?

BTW - is the same problem also in upgrade paths like 8.04 --> 10.04??

Thanks for testing Pekka, that's much appreciated. Yes the same problem exists when upgrading from LTS -> LTS. The new version in Lucid fixes the upgrade from karmic or hardy to lucid.
