I upgraded from 17.04 to 17.10 just yesterday and I was affected from the same issue.
I'm sorry to say, @mitya57, you intentionally broke the qDebug _default_ behaviour (and Fedora as well). qDebug()'ing something should result in printing in the console output. If there's issues with some applications that result in too much verbose output, should be fixed in those applications, not shutting up the whole QT qDebug. Anyway, this should be warned to the user in some way during the upgrade. just my 2 cents. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1731646 Title: missing qDebug output when creating QT applications Status in qtbase-opensource-src package in Ubuntu: Invalid Bug description: This bug seems to be connected to: https://bugzilla.redhat.com/show_bug.cgi?id=1227295 in the above link I have found a workaround for the problem.
