Public bug reported:
For about a week the update manager crashes while initializing the
package information.
I'm a bit helpless because a bug report (using ubuntu bug) could not be
generated and apt-get update does also not work. I will provide any
information I have and will do furhter analysis if you give me
instructions.
The unity panel contains a notification icon stating that problems
occured while running the update-manager. The user shall run the update-
manager manually (1) or run apt-get in a terminal (2). As mentioned
before there was a problem when running ubuntu-bug (3).
= 1 run the update-manager manually =
The application displays an error message and states a bug report should be
placed and the following error message should be attached:
---
E:Encountered a section with no Package: header, E:Problem with MergeList
/var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages,
E:Die Paketliste oder die Statusdatei konnte nicht eingelesen oder geöffnet
werden (Translation: The package list or the status file could not be read or
opened).

= 2 Run apt-get in a terminal =
Running apt-get in a terminal failed. There were several http 404 and
some GPG errors. You will find the apt.out in the attachment. I attached
/etc/apt/sources.list too.
= 3 Problems while running ubuntu-bug (this seems to be already reported
as Bug #996522) =
While trying to generate a bug report using "ubuntu-bug update-manager"
ubuntu-bug failed and the following error message was displayed:
---
Ungültiger Problembericht - Konnte Paket- oder Quellpaket-Namen nicht
bestimmen.
(Translation: Invalid issue report - couldn't determine package- or source-name)
---
= Version Information =
markus@markus-K52Jc:~$ lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04
I was not able to determine the version of the update-manager used
because "apt-cache policy update-manager" fails with the same error
message as "apt-get upgrade" does (see attachment). I tried to use the
Software Center without luck (It crashes just after start. The error
report can not be generated. The error is the same displayed by ubuntu-
bug.)
