The following problems might occur while you use the rpm utility to load or unload an IBM Informix package:

Problem. The command displays one of the following messages:
```
ERROR: You must be root to install product. 
ERROR: You must be root to uninstall product. 
```
Solution. Check that you are logged in as user root.
Problem. The command displays the following message:
```
ERROR: Failed to locate directory with write permissions.
```
Solution. Check that you are logged in as user root. Use the chmod command to grant write permission on the current directory and then run rpm again.
Problem. The command displays one of the following messages:
```
ERROR: User informix must exist to install product. 
ERROR: Group informix must exist to install product. 
```
Solution. Follow the instructions in Creating group informix and user informix to create the necessary user or group.
Problem. The command displays the following message:
```
package product is already installed 
ERROR: product.rpm cannot be installed 
```
Solution. If you want to reinstall the product, uninstall the previous package, as described in Uninstalling Using RPM (Linux).
Problem. The command displays the following message:
```
rpm: arguments to --relocate must begin with a / 
```
Solution. If you relocate the package installation directory by selecting a target directory other than the default, you must specify an absolute pathname for the target directory. For example:
```
rpm -iv --relocate /opt/informix=$INFORMIXDIR *.rpm 
```
