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. Fatal Python error: Aborted Current thread 0x00007f5866636700 (most recent call first): File "/usr/lib/ucsf-chimerax/lib/python3.8/site-packages/chimerax/ui/gui.py", line 157 in __init__ File "/usr/lib/ucsf-chimerax/lib/python3.8/site-packages/ChimeraX_main.py", line 577 in init File "/usr/lib/ucsf-chimerax/lib/python3.8/site-packages/ChimeraX_main.py", line 1015 in <module> File "/usr/lib/ucsf-chimerax/lib/python3.8/runpy.py", line 87 in _run_code File "/usr/lib/ucsf-chimerax/lib/python3.8/runpy.py", line 194 in _run_module_as_main Aborted (core dumped) 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. Thanks, Bing-Rui
