Description Honza Silhan 2016-03-18 15:59:57 UTC

We've identified your package for having `Requires(pre)` RPM flag without `Requires` [1]. `Requires(pre)` rpm tag could be interpreted wrongly, so to prevent any harm to Fedora users I am notifying you about this fact.

Any package that is specified in `Requires(pre)` could be freely removed. Citing from RPM pages:
```
If there are no other dependencies on the package providing /usr/sbin/useradd, that package is permitted to be removed from the system after installation(!)
``` [2]

If you really rely on dependency just during the installation process and your package don't necessary require the dependency for the proper run of your application then ignore this bug report and close it as NOTABUG. Otherwise add to your spec file additional `Requires` for the dependency, please.

Comment 1 Tom "spot" Callaway 2016-03-18 16:13:29 UTC

I think your check is faulty. Looking at the spec, this is what R-java has:

%package java
Summary: R with Fedora provided Java Runtime Environment
Group: Applications/Engineering
Requires(post): R-core = %{version}-%{release}
%if %{with_java_headless}
Requires(post): java-headless
%else
Requires(post): java

and R-java-devel:

%package java-devel
Summary: Development package for use with Java enabled R components
Group: Applications/Engineering
Requires(post): R-core-devel = %{version}-%{release}
Requires(post): java-devel

There is no Requires(pre) in the spec file at all.
