Xpra: Ticket #1410: xpra attach fails on vanilla Ubuntu Xenial Xerus

I have just installed vanilla Ubuntu Xenial Xerus, followed by xpra from the official repository (xpra v1.0.1-r14723).

To avoid the many errors/warnings I start the server the following way:

xpra --daemon=no --mdns=no --pulseaudio=no --opengl=no --notifications=no --printing=no start :1984

If I want to attach xpra :1984, xpra fails with a non identifiable error message.

The whole output given from

xpra --opengl=no --pulseaudio=no --notifications=no attach :1984 >error.log 2>&1

is attached to this ticket.

Fixed in r14791, v1.0.x backport in r14792.

You can find 1.0.2 beta packages with this fix here: http://xpra.org/beta As a temporary workaround, you could probably just install a fake "/usr/local/pactl" binary to pass the pulseaudio test that was returning the "None" value which caused the problem.

Please close if this works for you.

That worked, thank you! For reference, another solution is to install the pulseaudio packages: pulseaudio-utils pulseaudio jackd

(I was thinking setting pulseaudio=off disabled everything with pulseaudio completely but this does not seem to be the case ...)
