upgrade from Ubuntu 10.4 to 10.10 problem


I have been trying to upgrade from Ubuntu 10.4 to 10.10 and keep getting the following error message:
W:Failed to fetch http://archive.canonical.com/ubuntu/...curity/Release Unable to find expected entry restricted/binary-amd64/Packages in Meta-index file (malformed Release file?)
, E:Some index files failed to download, they have been ignored, or old ones used instead.

I have no idea how to deal with this.
Thanks for any help.
Brian

Have you updated your repos from 10.4? and how exactly are you trying to do this upgrade? What steps have you taken? More information=quicker solutions.

Let me preface this by saying I no longer use *buntu as the constant regressions were a headache for me. In my opinion (and many others) it would be better to move your /home to a separate partition and then do a fresh install. As long as you have the /home partition, all your settings will be maintained and you won't lose any documents. Of course, of you have any applications that are not in the repo's anymore, you won't be able to reinstall them unless you go outside the repo again.

Using update manager

So far I have simply been using the update manager and getting the error message I cited in my first post:

W:Failed to fetch http://archive.canonical.com/ubuntu/...curity/Release Unable to find expected entry restricted/binary-amd64/Packages in Meta-index file (malformed Release file?),
E:Some index files failed to download, they have been ignored, or old ones used instead.

I hadn't thought it would be necessary to move /home and do a fresh install, but I guess I could try that.

It is not _necessary_, but it is a good idea to have your /home on a separate partition for many reasons. First and foremost (IMO) is for trying out several distro's over a short period of time. But I also found it best for upgrading release based distro's. I have been using a rolling-release distro (PCLinuxOS) for a while now and have not had the regression problem I mentioned earlier.

So to reiterate, it is not necessary to move your /home and reinstall. But it is easier in the long run.

Oh, I also did a quick search and found that you may have this problem:
Check that your sources.list and mirror.list match up and that you're not trying to retrieve something from your mirror that you haven't actually mirrored.

Perhaps the command line would work. First install aptitude, if it's not already installed (via the command line, "sudo apt-get install aptitude"). Then, install gksu, then try pressing Alt-F2 and entering "gksu gedit" (this is to run the text editor gedit with root and/or superuser priviledges -- which works in Debian, though frankly I'm not sure about Ubuntu with its sudo setup). Anyway, from here open the file /etc/apt/sources.list. In it, replace the instances of "lucid" with "maverick" (lucid being the name of 10.04, and maverick being the name of 10.10). Having done this, save it, and close gedit. Then open a terminal, and type "sudo aptitude update". Then, "sudo aptitude install apt aptitude". Then, "sudo aptitude safe-upgrade". Finally, "sudo aptitude full-upgrade".

As always, backup your important files first. Note, if in any of the steps above with aptitude, you're given a warning that half your system will be eliminated followed by the question "Accept this solution? [Y/n/q/?]", then by all means press "q" and don't proceed. At that point, rather than feeling that you must have the latest, it's best to simply abide by the old maxim "If it ain't broke, why fix it?"
