Public bug reported: 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
Checking package manager Reading package lists... Done Building dependency tree Reading state information... Done Building data structures... Done Calculating the changes Calculating the changes 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. ** Affects: apt (Ubuntu) Importance: Undecided Status: New ** Tags: multiarch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1538080 Title: Old apt version blocks upgrade from 14.04.3 LTS to 15.04 due to "Unknown Multi-Arch type 'no'" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1538080/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
