Thx Ok, for some strange reasons the libs were not there. I reinstalled them again differently and now the situation is this:
marvin@X1-18:~$ telegram-desktop This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Available platform plugins are: dxcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb. Reinstalling the application may fix this problem.
