I am on Ubuntu 18.04 also experiencing this error. It does not appear that --sleep has any effect (tried values of 1, 5, 10, and 100). It looks like its just failing to start the server to begin with.
Simply running xpra start on my system also produces the same error.

Running bash -x run_scaled ... for me helped identify the problem.
I discovered that the xpra was exiting. Looking at its log:
$ more /home/joant/.xpra/:24349340.log
2019-01-05 02:19:23,641 Error starting Xvfb:
2019-01-05 02:19:23,641 [Errno 2] No such file or directory
On my (Debian stretch) system, sudo apt install xvfb fixed everything.
Issue fixed for me.
As per the comment by @wohali , I looked at the log and installed the packages that were relevant to the error message. However, this might or might not be relevant to fixing the issue for me.
More importantly, what I found was that I needed to pass environment variables before ./run_scaled. Also, I needed to give --sleep option to let the wine application start. So instead of doing,
./run_scaled WINEPREFIX=/foo wine application_name
I had to do
WINEPREFIX=/foo ./run_scaled --sleep=20 wine application_name
software that might help resolve some errors are,
gst-python2 python2-pycups python2-dbus xorg-server-xvfb xpra
@kaueraal Please fix the dependency list
I was able to fix this by installing xpra from the official site, instead of from the default Ubuntu sources. They don't have fantastic instructions though: https://xpra.org/trac/wiki/Download#Linux
FYI: as of xpra v3, you don't have to sleep to connect to a socket client to retry to connect until it succeeds .
Per @wohali on Fedora, install xvfb via:
sudo dnf install xorg-x11-server-Xvfb
This solved this issue for me.
Hello folks,
I am using run_scaled in my ubuntu with VMD and I am still experiencing this error. This occurred after I installed xpra. I'm curious if somebody else is experiencing this. Thanks in advance!

@mackevinbraza don't use outdated versions, please also see https://github.com/Xpra-org/xpra/wiki/Distribution-Packages
Xpra directly includes an equivalent tool since version 4.1. It is also called run_scaled and is part of the default Xpra installation.
Hence, this script here is deprecated and no longer maintained. I'm sorry that it took me quite long to officially announce it here. Thank you for your support and please continue your HiDPI journey with Xpra's tool!
