Also occurs on Zesty installations that have been upgraded from Yakkety. Unity8 fails to launch (classic black screen) and unity8.log shows the error: "character conversion failed"
This is due to incorrect multiple versions of boost being present on the system because they aren't removed when upgrading. Counted 6(six) different boost versions installed in Zesty because of taking the upgrade route through multiple Ubuntu versions. 'apt-get remove --auto-remove --purge' does not remove them so looks like a genuine dependency resolution problem when upgrading. Manually removing all the old boost versions works around the problem and allows Unity8 to work again. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1651735 Title: $ mir_demo_server --help fails with an exception Status in Mir: Invalid Status in mir package in Ubuntu: Invalid Bug description: $ mir_demo_server --help [2016-12-21 11:49:00.068655] mirplatform: Found graphics driver: mir:mesa-kms (version 0.25.0) [2016-12-21 11:49:00.069710] mirplatform: Found graphics driver: mir:mesa-x11 (version 0.25.0) [2016-12-21 11:49:00.069935] mirplatform: Found graphics driver: mir:stub-graphics (version 0.25.0) [2016-12-21 11:49:00.069954] mirplatform: Found graphics driver: throw-on-creation (version 0.25.0) ERROR: Throw location unknown (consider using BOOST_THROW_EXCEPTION) Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::logic_error> > std::exception::what: character conversion failed To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1651735/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
