Chimerax 1.2.5 Ubuntu 16.04 failed to start

Hello ChimeraX developer, I am trying to update ChimeraX from v1.1 to v1.2.5 on a Ubuntu 16.04 Linux machine, but Chimerax v1.2.5 failed to start with the following error message:
sudo apt-get install ~/Downloads/ucsf-chimerax_1.2.5_amd64.deb chimerax qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Thanks, Bing-Rui

Thank you for reporting this. There is a missing dependency on the libxcb-xinerama0 package. Please install it with: sudo apt install libxcb-xinerama0 and then try ChimeraX 1.2.5 again. This bug is also present in the current Ubuntu 18.04 and 20.04 downloads. It will be fixed within 24 hours. -- Greg On 6/13/2021 7:31 AM, Zhou, Bing-Rui (NIH/NCI) [E] via ChimeraX-users wrote:

I could downgrade to ChimeraX v1.1 and it works fine, just wondering what has changed in v1.2.5 and if there is a fix for this issue.
