Linux client starts with black screen, because of **CRASHING**:seccomp-bpf failure in syscall 0281


On Ubuntu 17.10 64-bit, the native Paperspace client hangs on a black screen.

It looks like it is failing to start because of this backtrace. It can be worked around by starting Paperspace with QTWEBENGINE_DISABLE_SANDBOX=1.

Thanks for reporting. There’s a fix going out for this in the next release.



Just wondering if this is fixed yet? I’m still getting same problem on my Linux machine.


hmm did the app update successfully to the most recent version when you opened it? In any case, try downloading the latest version from here. The bug ticket is closed but it’s certainly possible we’ll need to re-open it.
