Comment 14 for bug 1445688

For wesnoth-1.12, this was fixed with the 1:1.12.2-1 upload, which is both in vivid and wily, closing the tasks there. Precise does not have the package at all. For trusty and utopic, these packages were provided by the ubuntu-backports project https://launchpad.net/ubp ; you'll need to file a request with them to update wesnoth-1.12 (see https://wiki.ubuntu.com/UbuntuBackports for more details on the backports update process).
