The Qt5 port of the user interface is in good shape, successful tests have been made with up to Qt5.5. The development still happens in a branch:[in a branch] (, but that will be merged soon into the main trunk, and the Qt4.x version will become a separate branch.

In the meantime, a binary package for Ubuntu 14.04 or 15.10 on amd64 architecture is available in an experimental repository, which can be added to /etc/apt/sources.list.d/manitou.list:

deb http://manitou/apt trusty experimental

The package is manitou-ui, version 1.5.0. It’s built with Qt-5.2.1 on Ubuntu 14.04.
