12.2.2.3. Unresolved Dependency

RPM packages may sometimes depend on other packages, which means that they require other packages to be installed to run properly. If you try to install a package which has an unresolved dependency, output similar to the following is displayed: 
error: Failed dependencies:
        bar.so.2 is needed by foo-1.0-1
Suggested resolutions:
	bar-2.0.20-3.i386.rpm
Copy to Clipboard Toggle word wrap
If you are installing a package from the Red Hat Enterprise Linux CD-ROM set, it usually suggest the package(s) needed to resolve the dependency. Find the suggested package(s) on the Red Hat Enterprise Linux CD-ROMs or from Red Hat Network , and add it to the command: 
rpm -ivh foo-1.0-1.i386.rpm bar-2.0.20-3.i386.rpm
Copy to Clipboard Toggle word wrap
If installation of both packages is successful, output similar to the following is displayed: 
Preparing...                ########################################### [100%]
   1:foo                    ########################################### [ 50%]
   2:bar                    ########################################### [100%]
Copy to Clipboard Toggle word wrap
If it does not suggest a package to resolve the dependency, you can try the -q --whatprovides option combination to determine which package contains the required file. 
rpm -q --whatprovides bar.so.2
Copy to Clipboard Toggle word wrap
To force the installation anyway (which is not recommended since the package may not run correctly), use the --nodeps option.
