Good morning, I tried to install chimera X for Ubuntu 16 but I have the following problem. (base) da.acevedo10@colab14:~$ sudo apt-get install /home/UANDES/da.acevedo10/chimerax-daily.deb Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'ucsf-chimerax-daily' instead of '/home/UANDES/da.acevedo10/chimerax-daily.deb' Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ucsf-chimerax-daily : Depends: ffmpeg but it is not installable E: Unable to correct problems, you have held broken packages. I really appreciate if you can tell me why I can't install chimera x Cordialmente, Dorian Armando Acevedo Castro COBO - Computational Bio- Organic Chemistry Bogotá cobo.uniandes.edu.co<http://cobo.uniandes.edu.co/> Estudiante Doctorado Ciencias-Química.
