I've recently set up some fresh new Fedora installations (both 27 and 28), and installed Google Chrome Beta (67.0.3396.62) by downloading them from the official location (aka google-chrome-beta_current_x86_64.rpm).

In both installations, both `rpm -Uvh <package.rpm>' and `dnf install <package.rpm' yield the same result: the package is installed correctly, but the post-installation task fail to run.

Running `dnf reinstall <package.rpm>' doesn't help, and it is only when I run `dnf reinstall google-chrome-beta' (ie. by package name, not actual file) that things run correctly:

I haven't dug very deep, but I wonder if this can impact the delivery of package updates to users whose installations have proceeded like mine.
