Here's a possible fix. I tested it on bionic and it seems it works. For my xenial machines I had to workaround it disabling completely the check because the glibc there doesn't behave the same way.
So I'm attaching a debdiff with the proposed upload for bionic; it would be nice if someone could sponsor it, thanks in advance. ** Patch added: "multitail -fix for ttyname() based check" https://bugs.launchpad.net/ubuntu/+source/multitail/+bug/1669578/+attachment/5061383/+files/multitail_fix.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1669578 Title: Get ttyname() to work properly in containers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1669578/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
