It happens on jammy kernel, which launchpad builder uses. So likely you are running docker on some old kernels.
I think it happens when the kernel doesn't implemented close_range syscall. However I haven't figured out why calling close_range will cause the process to hang. More interestingly, I find the faked process becomes zombie state when run inside a subshell, as the fakeroot tests use. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068702 Title: fakeroot test hangs on launchpad builder To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fakeroot/+bug/2068702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
