Is Debian 9.3 supported?

[stealth]

Hello,

I’m testing nxserver on debian 9.3 without any success (many segfaults) there is a way for using NoMachine 6.0.7 on the latest Debian ?

Thanks

[Britgirl]

Although we haven’t yet added it to our official list in the download section, NoMachine runs on Debian Stretch without any problems provided you are not using Wayland protocol. Wayland will be supported in an upcoming maintenance: https://www.nomachine.com/FR10N03221.

With the package from your website ? Here it segfaults permanently

I’m using XFCE as far that I known wayland is not supported with XFCE4

There are no symbols in the backtrace. Are you sure that you specified all the gdb options mentioned in the article?

Please execute following command:

sudo gdb  -core=<path_to_core_file>  -se=/usr/NX/bin/nxnode.bin

Maybe this can help, strace (nxnode.bin runs in root)

Can you try disabling Lock screen in server configuration (https://www.nomachine.com/AR07M00851) and let us know if it helps?
