Uninstalling - Red Hat ENTERPRISE LINUX 4 System Administration Manual

Chapter 15. Package Management with RPM
15.2.2.3. Unresolved Dependency
RPM packages can, essentially, 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
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 the Red Hat FTP site (or mirror), and add it to the command:
rpm -ivh foo-1.0-1.i386.rpm bar-2.0.20-3.i386.rpm
If installation of both packages is successful, output similar to the following is displayed:
Preparing...
1:foo
2:bar
If it does not suggest a package to resolve the dependency, you can try the --redhatprovides
option to determine which package contains the required file. You need the rpmdb-redhat package
installed to use this option.
rpm -q --redhatprovides bar.so.2
If the package that contains bar.so.2 is in the installed database from the rpmdb-redhat package,
the name of the package is displayed:
bar-2.0.20-3.i386.rpm
To force the installation anyway (which is not recommended since the package may not run correctly),
use the --nodeps option.

15.2.3. Uninstalling

Uninstalling a package is just as simple as installing one. Type the following command at a shell
prompt:
rpm -e foo
Note
Notice that we used the package namefoo, not the name of the original package
filefoo-1.0-1.i386.rpm. To uninstall a package, replace foo with the actual package
name of the original package.
