2.0 Updating the Identity Manager Components on Linux

The following considerations apply before you update Identity Manager components on Linux platforms:

Ensure that you install the zip and unzip RPM packages.

NOTE:NetIQ recommends that you obtain the dependent packages from your operating system subscription service to ensure continued support from your operating system vendor. If you do not have a subscription service, you can find the recent packages from a website such as http://rpmfind.net/linux.
(Conditional) If you are updating the Identity Manager from 4.8 to 4.8.4 directly, then you must apply the Identity Applications 4.8.0.1 patch before 4.8.4 version in the following scenarios:
- eDirectory 9.2 and Identity Applications 4.8 are installed on the same server.
- iManager 3.2 and Identity Applications 4.8 are installed on the same server.
- Identity Applications 4.8 and PostgreSQL are installed on the same server.
The Identity Applications 4.8.0.1 patch resolves the dependencies between the NGINX module and the OpenSSL libraries. For instructions on applying the patch, see the NetIQ Identity Applications 4.8.0 Hotfix 1 Release Notes.

If you do not apply the Identity Applications 4.8.0.1 patch, the Identity Vault update fails and the installer reports the following error message:
```
Problem: patterns-edirectory-9.2.2-6.x86_64 requires netiq-openssl = 1.0.2u, but this requirement cannot be provided not installable providers: netiq-openssl-1.0.2u-32.x86_64[edirectory-9.2.2] 
Solution 1: deinstallation of netiq-nginx-1.14.2-1.x86_64 
Solution 2: do not install patterns-edirectory-9.2.2-6.x86_64 
Solution 3: break patterns-edirectory-9.2.2-6.x86_64 by ignoring some of its dependencies
