Old apt version blocks upgrade from 14.04.3 LTS to 15.04 due to "Unknown Multi-Arch type 'no'"

[Jan van Haarst]

I'm trying to update a 14.04.3 LTS machine to 15.04.
In that process, I get the following message :
------
Unknown Multi-Arch type 'no' for package 'compiz-core'
Unknown Multi-Arch type 'no' for package 'compiz-gnome'
Unknown Multi-Arch type 'no' for package 'compiz-core'
Unknown Multi-Arch type 'no' for package 'compiz-gnome'
Unknown Multi-Arch type 'no' for package 'compiz-core'
Unknown Multi-Arch type 'no' for package 'compiz-gnome'
Unknown Multi-Arch type 'no' for package 'compiz-core'
Unknown Multi-Arch type 'no' for package 'compiz-gnome'
You may want to run apt-get update to correct these problems

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

------

This problem is caused by apt, according to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=759099 , this was solved in apt 1.0.7.
The version installed with trusty-updates is 1.0.1ubuntu2.10, so without the fix.

Is there a way to upgrade to fix this ?
I would really like to convert this machine into a non LTS machine, without having a reinstall which would make my users unhappy.

The failure to calculate the upgrade is not related to the "Multi-Arch type" issue you've identified. Please include the contents of '/var/log/dist-upgrade' or run 'apport-collect 1538080' so we can identify the real issue.
