It looks like the problem is the unmet dependency on ffmeg.  It says that ffmpeg is not installable.  The question is why?  So first try "sudo apt-get install ffmeg" to see if you can get more information.  Read apt-get manual page for clues, you might to "google".  If you can get ffmpeg installed, then installing ChimeraX should work.

If you can't get ffmeg to install.  Then try adding an additional argument to "apt-get install" to skip trying to install ffmeg.  You won't be able to make movies, but the rest of ChimeraX should work.  I'd first try "apt-get install --ignore-missing", and if that didn't work, "apt-get install --fix-broken".  Reading the manual page for apt-get could help here too.

    Good luck,

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

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,
