Hi, unfortunately the new release did not solve the problem with new nextcloud client. With x2goserver 4.1.0.3 and nextcloud-client 2.5.0 in an lxc container I encounter following error : Gkr-Message: 20:08:21.755: secret service operation failed: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. [1044:1221:1130/200822.207292:ERROR:gl_surface_qt.cpp(241)] GLX 1.3 or later is required. [1044:1221:1130/200822.207353:ERROR:gl_surface_qt.cpp(371)] GLContextHelper::getEGLDisplay() failed.
