Dropbox not working

Yesterday, the dropbox in the container was updated to version 85.4.155. And it does not start anymore. CentOS 7.
Error: ImportError: libatomic.so.1: cannot open shared object file: No such file or directory.

Detailed:
!! dropbox: fatal python exception:

Start by reproducing the Dropbox startup failure in the CentOS 7 container and inspect the reported ImportError for the missing libatomic.so.1 library. Trace the container's dependency setup and confirm that Dropbox starts successfully without the missing-library error.
