Verifying License Fails With A Missing Shared Library File "Unbound.so"

Symptoms:

Attempting to verify the license fails with this error:

# /usr/local/cpanel/cpkeyclt --force

CONFIG_TEXT: /usr/local/cpanel/cpkeyclt: error while loading shared libraries: /usr/local/cpanel/3rdparty/perl/530/lib/perl5/cpanel_lib/x86_64-linux-64int/auto/DNS/Unbound/Unbound.so: cannot open shared object file: No such file or directory

Cause:

The missing shared library file above is part of this package:

# rpm -qf /usr/local/cpanel/3rdparty/perl/530/lib/perl5/cpanel_lib/x86_64-linux-64int/auto/DNS/Unbound/Unbound.so

CONFIG_TEXT: cpanel-perl-530-DNS-Unbound-0.20-1.cp1186.x86_64

There are quite a few situations where that package might accidentally be erased from the server. One such occasion is where another package that has cpanel-perl-530-DNS-Unbound as a dependency gets uninstalled. For instance, uninstalling either of these two packages would also uninstall it:

CONFIG_TEXT: cpanel-unbound

CONFIG_TEXT: openssl

Resolution:

Running the following script should resolve this issue:

# /scripts/check_cpanel_rpms
