Public bug reported: What happened: 1) Install a container system (eg Docker, LXD) - I'm using Docker 2) Create a container which is Ubuntu 18.04 3) Install a Qt app, eg qtcreator, inside the container 4) Run the container so that it shows the hosts X11 socket 5) Notice that the application fails to start
What I expected to happen: At step 5 for the application to start. Note that the same steps work fine for Ubuntu 16.04 and 17.10 - and if it matters my host is 17.10. Here is a stacktrace of the crash https://pastebin.ubuntu.com/p/WKKGmxqqSx/ Here is a Dockerfile that reproduces the issue https://pastebin.ubuntu.com/p/nzmJRfPYVc/ to use this make a Dockerfile in an empty folder with the pastebin contents, then simply run the following commands in that folder $ sudo apt install docker.io $ sudo docker build -t qtbug . $ sudo docker run --rm -ti -e DISPLAY --net=host --cap-add=SYS_PTRACE --security-opt seccomp=unconfined qtbug This should enter you into the gdb session. ** Affects: qtbase-opensource-src (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774739 Title: Running Qt apps inside a 18.04 container crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1774739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
