For reference evolution-plugins 2.32.2-0ubuntu7 is a version from Natty and maybe a leftover from a previous upgrade.
Bug 1036743 contains an history of the upgrades of the system.

I had this same problem I resolved it by removing the evolution-plugins package from the stale distribution.

sudo apt-get remove evolution-plugins

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

Hello Ashutosh, or anyone else affected,

Accepted nspr into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nspr/4.8.9-1ubuntu2.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

SRU verification for Precise:
I have reproduced the problem with libnspr4 4.8.9-1ubuntu2.1 in precise-updates and have verified that the version of libnspr4 4.8.9-1ubuntu2.2 in -proposed fixes the issue.

I did the following verification.
- Verification on Precise following the second test case in the description
- Verification on Lucid:
  - Installed language-support-translations-en/jaunty language-support-en/jaunty language-support-writing-en/jaunty
  - Without -proposed enabled, the calculation of the upgrade to Precise succeeds but evolution is removed
  - With -proposed enabled, the calculation of the upgrade to Precise succeeds and evolution is upgraded
- Verification on Oneiric:
  - I followed the same steps than test case 2 and upgraded to Precise
  - Without -proposed enabled, calculation of the upgrade failed
  - With -proposed enabled, calculation of the upgrade succeeds and the package language-support-translations-en and language-support-en are removed during the upgrade.

Marking as verification-done

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package nspr - 4.8.9-1ubuntu2.2

---------------
nspr (4.8.9-1ubuntu2.2) precise-proposed; urgency=low

  * Add additional Conflicts: on the obsolete evolution-documentation-*
    packages, which are held back on some users' systems despite being
    obsolete before 10.04; and also on the matching
    language-support-translations-* and language-support-* packages. This
    should ensure libnspr is getting upgraded, instead of evolution being
    held back. LP: #1036794.

indeed its all fixed now, just checked update-manager and it is working
seamlessly now, great work team, thanks to you all, saved me from a lot of
hassles, thank you all one again

Thus far things are looking good.
Enabled the proposed ,did a cycle ,
then got the regular precise back going again , update checks , installs etc seem
to be happy. Even after a reboot we're still here , and put propose back to sleep
and things. I'll give things a closer inspection next time I'm awake.

Looks like that all did the trick though :)

I am still having a couple of issues running different parts - apologies for being rubbish, but can someone just list the commands I need to run/things I need to enable in one place so I can go through in order.

Thanks.

I second what Peter says. I think I followed the steps outlined, but I'm not sure.

The fix in nspr (4.8.9-1ubuntu2.2) is less than ideal as users will hit this:

The following extra packages will be installed:
  libnspr4
The following packages will be REMOVED:
  language-support-en language-support-fr
The following packages will be upgraded:
  libnspr4 libnspr4:i386 libnspr4-0d libnspr4-0d:i386

Which will result in a scary message from update-manager asking to do a "partial upgrade", and will probably break unattended-upgrades.

The issue in comment #15 will affect anyone who has upgraded from lucid to precise, and anyone who has upgraded from natty to oneiric to precise, so it's not limited to people who have been updating since jaunty.

Hello Ashutosh, or anyone else affected,

Accepted nspr into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nspr/4.8.9-1ubuntu2.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Tested the new nspr (ubuntu2.3) in 10.04.4 to 12.04 upgrade with media only, upgrade succeeded so the change doesn't regress the upgrade.

manual verification from oneiric to precise and lucid to precise with nspr 4.8.9-1ubuntu2.3 is ok.
calculation of the upgrade is successful, language-support-translations-en is removed during upgrade.
for oneiric if evolution-plugins/natty and evolution-common/natty are installed, evolution is installed during the upgrade instead of blocking it.
update-manager on precise with -proposed enabled with language-support-*-en installed doesn't show any scary popup.
automated test ran for desktop, server and server-tasks for lucid and oneiric to precise and nothing found.

This bug was fixed in the package nspr - 4.8.9-1ubuntu2.3

---------------
nspr (4.8.9-1ubuntu2.3) precise-proposed; urgency=low

  * language-support-LANG was still around in 11.04 so the previous change
    is requiring a dist-upgrade for any user who upgraded from 11.04 to 11.10
    and then to 12.04, instead of being limited to machines that were
    originally installed with 9.04 as was planned.
    Removing language-support-LANG from the Breaks, which should resolve the
    issue for these users while still removing language-support-translations
    on systems. (LP: #1036794)

Hey,
Sorry to be a pain, but just to reiterate, can someone spell out what I need to enter to fix this, as I am still unable to resolve the issue.

Thanks.

I was not able to excute the steps in the documention. It was probably because I did not undersatnd them well enough. While I'm a Linux user, I'm not all the knowledgable about admin tasks. It's a credit to the distribution that I have been able to use the system with very few issues for a numbers of years without having to know all that much about admin. In any case I did get through the update and I waited for another update to occur to be sure that issue was fixed and yes, all is well.

My feedback...
In cases like this a litltle more detail in the directions would be helpful for less expert users. If the specific example had been used in addition to the general directions, I think it would have solved my issue and maybe that for a few others, too.
I was very impressed by the response to the issue. Thank you!!

Dave

This bug was fixed in the package nspr - 4.8.9-1ubuntu3

---------------
nspr (4.8.9-1ubuntu3) quantal; urgency=low

  * Reupload to quantal.

nspr (4.8.9-1ubuntu2.3) precise-proposed; urgency=low

  * language-support-LANG was still around in 11.04 so the previous change
    is requiring a dist-upgrade for any user who upgraded from 11.04 to 11.10
    and then to 12.04, instead of being limited to machines that were
    originally installed with 9.04 as was planned.
    Removing language-support-LANG from the Breaks, which should resolve the
    issue for these users while still removing language-support-translations
    on systems. (LP: #1036794)

nspr (4.8.9-1ubuntu2.2) precise-proposed; urgency=low

  * Add additional Conflicts: on the obsolete evolution-documentation-*
    packages, which are held back on some users' systems despite being
    obsolete before 10.04; and also on the matching
    language-support-translations-* and language-support-* packages. This
    should ensure libnspr is getting upgraded, instead of evolution being
    held back. LP: #1036794.

nspr (4.8.9-1ubuntu2.1) precise-proposed; urgency=low

  * Add Breaks: evolution-plugins (<< 3.2.0-0ubuntu2) to libnspr4,
    required to get the dist-upgrader to resolve lucid -> precise.
