Ubuntu 15.04, Vivid, will be reaching End of Life this week - at which point in time upgrades will be performed from Trusty to Wily. I'm in the process of testing upgrades from Trusty to Wily and provided they are successful, I'll be setting Vivid as End of Life early (only in the meta-release files) so that the upgrade path will be to Wily. I'll comment on this bug after making such a change.
