Cannot update to ubuntu 11.10

[Josema]

When updating I met an error screen reading:

After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore.
This indicates a serious error, please report this bug using the command 'ubuntu-bug update-manager' in a terminal and include the files in /var/log/dist-upgrade/ in the bug report.

I tried to run ubuntu-bug update-manager in the terminal, a new error screen pops up reading: El paq
uet update-manager no existeix (in English: The update-manager package does not exist).

The files I have in /var/log/dist-upgrade/ are 5: apt.log, apt-clone_system_state.tar.gz, lspci.txt, main.log and term.log. They have the following information.

1- apt.log:
Log time: 2011-10-13 18:22:03.958467
Log time: 2011-10-13 18:22:26.727765
Log time: 2011-10-13 18:26:13.922595

2- apt-clone_system_state.tar.gz: this is a tar file.

Thank you very much in advance for your attention,

I hope it will help to solve the bug.

[Jamie Strandboge (jdstrand)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

[Ricky Bulalakaw (rbulalakaw)]

I have a similar problem... I try to update from Ubuntu 11.04 to 11.10. It tries to update, but it gives an error message similar above.

When I try to follow the "command 'ubuntu-bug update-manager' in a terminal," I get message that my Ubuntu package is not genuine, and that my problem will not be reported.

The files on my /var/log/dist-upgrade/ directory are:

I hope this helps in resolving the inability of my desktop to upgrade. I had Ubuntu in this desktop since version 10.10. The internet connection is through our university which requires proxy, I did not have problems before upgrade relating to the proxy.

Thanks.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Josema (jmagullopastor)]

It seems basic and strange but it worked for me. Try to download the Desktop CD and install Ubuntu 11.10 from there, this way I did no found the error I hab from the Update manager.
