[SOLVED] Dependency Resolution Fails on Installed Library

Issue

I'm trying to install a rpm and get following error:

---> Package geramer-server.x86_64 0:3.6.0.117-1 will be an update
--> Processing Dependency: libcrypto.so.10(libcrypto.so.10)(64bit) for package: geramer-server-3.6.0.117-1.x86_64
---> Package geramer-ui.x86_64 0:3.6.0.98-1 will be updated
---> Package geramer-ui.x86_64 0:3.6.0.117-1 will be an update
--> Finished Dependency Resolution
Error: Package: geramer-server-3.6.0.117-1.x86_64 (/geramer-server-3.6.0.117.x86_64)
           Requires: libcrypto.so.10(libcrypto.so.10)(64bit)

My first thought was that libcrypto.so is not installed. But this is not the case, see:

$ ldconfig -p | grep libcrypto.so
    libcrypto.so.10 (libc6,x86-64) => /usr/lib64/libcrypto.so.10

It also exists on disk:

$ ls -l /usr/lib64/libcrypto.so.10
lrwxrwxrwx 1 root root 18 Dec  4 13:11 /usr/lib64/libcrypto.so.10 -> libcrypto.so.1.0.0

And also RPM knows about it:

$ yum whatprovides "*/libcrypto.so.10"
Loaded plugins: product-id, rhnplugin, subscription-manager
*Note* Red Hat Network repositories are not listed below. You must run this command as root to access RHN repositories.
openssl-1.0.0-25.el6_3.1.x86_64 : A general purpose cryptography library with TLS implementation
Repo        : installed
Matched from:
Filename    : /usr/lib64/libcrypto.so.10

So any ideas what I'm missing?

Solution

Dependencies have module names, which are listed in parenthesis to prevent collisions between packages. However, openssl in RHEL or openssl-libs on Fedora provide libcrypto.so.10 with four different module names for two architectures:

$ rpm -q --provides openssl-libs | grep libcrypto.so.10
libcrypto.so.10()(64bit)
libcrypto.so.10(OPENSSL_1.0.1)(64bit)
libcrypto.so.10(OPENSSL_1.0.1_EC)(64bit)
libcrypto.so.10(libcrypto.so.10)(64bit)
libcrypto.so.10
libcrypto.so.10(OPENSSL_1.0.1)
libcrypto.so.10(OPENSSL_1.0.1_EC)
libcrypto.so.10(libcrypto.so.10)

It seems to be the case for CentOS too, which is RHEL based.

In your case, openssl seems to provide only libcrypto.so.10 without any module name, making geramer-server believe that dependency is missing as it requires libcrypto.so.10 from module libcrypto.so.10.
