Upgrade 10.04 -> 10.10 failed due to "the essential package 'ubuntu-minimal' can not be found anymore" ((in|gb).archive.ubuntu.com releated?)

Same message. Program asked me to send this file: see attachment

+Affects me.

Additional note: I'm using UNR.

Affects me as well. Attached the dist-upgrade logs.

Thanks for your bugreport.

Could you please run (in a terminal):
$ head /var/lib/apt/lists/*main*Package*
and attach the output here? I suspect there is something that prevented the correct download of the packages files in your network connection (a provider, a proxy, a pay-wall, etc).

Sorry, the installation is already whiped out. But I am pretty sure that it
is a proxy-issue. Since when I moved the laptop to my home (no proxy) the
update ran without any issues... I think I posted it somewhere on the
bugreport that I thought the module which does upgrade-web-connections can
not handle some proxy settings correctly (I also found an error-report from
wget where a internet-addres in the form of
http://user:password@address...:8080
(where the 8080 was the proxy-port) gave an error message stating the 'port
was invalid' where I assumed that the program maybe did a wrong
interpretation of the first colon and tried to use password as a port
number... (?)

what do you say?

Thanks for your inputs Michael. I have attached the o/p you requested.

I am trying to upgrade my home PC and I am pretty sure that I have not enabled any proxy or firewall here in my home network (at least knowingly).

Please let me know if you need any further info.

Hello Vishal,

could you please try to change the mirror in your sources.list from
 http://in.archive.ubuntu.com/ubuntu/
to http://archive.ubuntu.com/ubuntu (e.g. via System/Administration/Software sources)
and see if that helps?

Same problem for me - I've attached my output from $ head /var/lib/apt/lists/*main*Package*

Same for me, 10.04 to 10.10, here is my dist-upgrade contents

"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 against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report."

This works for me now. Wondering if it is related to the fix reported in https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/657700

Jon,

I think my bug is a dupe of this one. I noticed that the upgrading info / release notes warned about release candidate status prior to installation failing, but they presented mature documentation when installation proceeded (which it is doing now). I wonder whether some of the mirrors are taking a bit longer to refresh, or my CDROM was from a slightly old torrent?

Hi Michael,

Changing the mirror in sources.list worked for me. I was able to successfully upgrade it.

Thanks for your help!

I'm in the UK, and have this problem - should I try another mirror?

Dianne: That's what seems to have fixed it for me; Go to System ->Administration->Software Sources (or System->Administration->Update Manager->Settings) On the first tab, "Software Sources" (in 10.10) look at the list Download from: hit other, then try hitting the "Select Best Server", which I think pings a bunch of mirrors to find the one with the lowest latency (~ closest to you). See if that helps, then try something sensible off the list.

@Dianne, are you using gb.archive.ubuntu.com ?

Synaptic shows "server from United Kingdom"

Changing to another server has fixed it for me - thanks! I need my laptop updated to run a demo on Saturday. :)

all you need to do is change the server. it worked for me ^_^ already upgrade from 10.04 to 10.10 just now.

go to System > Administration > Update Manager > Settings > Ubuntu Software (tab) > Download from :

then change it to "Others". it will ping for the nearest and fastest server near you. or you can manually choose it if you want.
and then upgrade process run without problems :)

:This works for the user from India:
Changing the software sources of update-manager to choose best server solves the issue.
Go to System -> Administration -> Update Manager -> Settings -> Ubuntu Software (First Tab) -> Download from :
Select "Others" and Click "Select Best Server"-> Choose server.

After you can start upgrading to Ubuntu 10.10 without any hassles :)

I too ran into this issue. I worked around it by reading comments from other users on this page.

We use a proxy script at our workplace. I have specified the script URL in the "Automatic proxy configuration" setting of [System->Preferences->Network Preferences]. I extracted the HTTP proxy details from the script and set it in the HTTP proxy field of "Manual proxy configuration" setting of [System->Preferences->Network Preferences]. After this change, my upgrade worked fine (actually it is still going on but it has gone past the point where I used to see the problem). I'll restore the network preferences after the upgrade.

I've ran across this issue using local repos with non-standard ports. ie:

deb http://192.168.2.2:9999/ubuntu/ karmic multiverse

changing it to a different server worked for me!
