[Solved] impossible upgrade squeeze->wheezy

[bxdfr]

Hello, i try to upgrade my squeeze to wheezy

When i do:

Code: Select all

apt-get dist-upgrade

I have this message

Code: Select all

 E: Could not perform immediate configuration on 'default-jre'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

So i try this:

Code: Select all

apt-get -o APT::Immediate-Configure=false dist-upgrade

But i have this message:

Code: Select all

E: Could not perform immediate configuration on 'phonon-backend-vlc'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

I don't understand this last message because phonon-backend-vlc is not installed on my debian squeeze.

I tried with aptitude, but no more chance.

here my sources.list for squeeze:

Code: Select all

here my sources.list to upgrade to wheezy:

If you want Wheezy (Testing), you must change all the "squeeze" pointers that you have in your sources.list file to wheezy. Then, you have to issue an:

Code: Select all

# apt-get update

After that, you issue the actual dist-upgrade command. Also, be aware that some packages may need to be upgraded first before all the others. As far as I can remember, dpkg, apt and the kernel are among them. So, if I remember well, you have to issue the command:

Code: Select all

apt-get install dpkg apt linux-image-****

Please check which kernel version Wheezy uses.

Note:
I strongly suggest you to read about the upgrade procedure as this may change between major version upgrades, and as I also highlighted before, I am trying to recall from memory.

Thank you!!!
your

Code: Select all

apt-get install dpkg apt linux-image-****

saved me.

After that i did an

Code: Select all

apt-get dist-upgrade

that worked partially
and with

Code: Select all

aptitude dist-upgrade

it finally performed the upgrade.

Hope it works out for you. I have a feeling I would be pulling my hair out by the roots afterward if I did that on my machine.
