All code is the same regardless of archs, but the commit mentioned there is Mac specific so those code paths are not used on Linux.
Another idea would be, if you don't mind adding and removing PPAs and possibly needing to start over with your rootfs (if something goes badly wrong), to try stable phone overlay PPA from: https://launchpad.net/~ci- train-ppa-service/+archive/ubuntu/stable-phone-overlay/ - it includes Qt 5.6.1 which obviously has almost a year worth of newer fixes. sudo add-apt-repository ppa:ci-train-ppa-service/stable-phone-overlay sudo apt update sudo apt dist-upgrade To downgrade: sudo apt install ppa-purge sudo ppa-purge ppa:ci-train-ppa-service/stable-phone-overlay Or you could simply try Ubuntu 16.10 which has the same Qt 5.6 version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629792 Title: udpsocket ready read not fired on arm64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1629792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
