Something is probably wrong with your client setup if you don't have a valid XDG_RUNTIME_DIR. Your log sample is also a bit garbled.

v6.0.1 will handle this more gracefully: 3d647b43d00ad4b4e28e3a8d5b0c0c7f7111ac61 Though this won't fix your issues with XDG_RUNTIME_DIR being missing - don't expect miracles.

Yes, issue still exist, when I upgrade to xpra v6.1-r35687 (g929d991be7) beta.

That's expected, that version is older than the commit above. Either build from source or wait for new beta builds to be available. Or better yet, fix your dbus and XDG_RUNTIME_DIR issues. This should not be happening. The commit only papers over it.

cadem commented 6 months ago

Which version the dbus issue will be fixed in?

And I found the workaround way: launch the client as follow: dbus-run-session xpra attach :100.

The fix is in xpra, the next crop of builds will have it.

So your client doesn't have dbus running? Strange.

cadem commented 6 months ago

maybe so. I setup ubuntu desktop in a docker, dbus maybe is missing.

You should have mentioned that in the very first comment, save us all a lot of time.

eried commented 2 months ago

Hi @cadem what was the solution at the end? I am getting the same errors, I guess the system does not has dbus either

totaam commented 2 months ago

FWIW: with 6.2 and later, you can run with --no-dbus: 28f4d1dfaacf43e1075ba74188e951bd96fc6065

totaam commented 2 months ago

Anyone landing here is probably using an out-of-date package - see https://github.com/Xpra-org/xpra/wiki/Distribution-Packages

The workaround was included in v6.1.1: 702f35259aebf0377dc375e34060946b46a4cb79 which has been released.

eried commented 2 months ago

Hi, thanks, I am using 6.1.1-ro, but still getting this error. I will check once 6.2 gets released with the --no-dbus option :)

totaam commented 2 months ago

@eried are you sure that you have 6.1.1 running? What is the full output of xpra --version? Looking at the 6.1.1 version of this file: https://github.com/Xpra-org/xpra/blob/v6.1.1/xpra/platform/posix/keyboard.py#L46-L54 The fix is present!?
