Which deb package did you try, the Ubuntu 16.04 version or the 18.04 version?

[huatiger3@…]

Greg, Thank you
From http://www.cgl.ucsf.edu/chimerax/download.html
Ubuntu 16.04 and 18.04 seem to show the same deb package.

They are different. But you're right they should have different names. I'll work on that. I'm still curious which one did you try?

[huatiger3@…]

Greg,
I used the 18.04. Please see attached.
Thank you
John

So I'm not able to reproduce this error using a Ubuntu 19.04 virtual machine, but even if I could, it wouldn't work due to an explicit dependency on llvm6 and only llvm8 is available as far as I can tell for Ubuntu 19.04. So my recommendation is to use the Generic Linux daily build.

I'm going to take this opportunity to review if that dependencies are actually needed, and will get back to you about that.

Also, could you send me the output from "dpkg-deb -I ucsf-chimerax_0.91_amd64.deb"? And to double check, you are running on a 64-bit system, right?

[Greg Couch]

The package dependencies are reasonable.
