Apache won't load and "Document failed to print" after upgrade to OES 2018

After upgrading to OES 2018, sending a print job thru the Windows iPrint Client returns the error:

Document failed to print

iPrint Client properties, iPrint document status shows "Creation failed" error

ipsmd (Print Manager) and idsd (Driver Store) are running fine.

Apache is not loaded.  When loading Apache, the following is returned:

2. Compare the working and non-working output to the ldd command.  In the above scenario, the 3rd line shows a library linked to an incorrect file:

libssh2.so.1 => /lib64/libssh2.so.1 (0x00007f62eac5f000)

3. Do a listing on the incorrect module:

l /lib64/libssh2.so.1

lrwxrwxrwx 1 root root 49 Nov 21 2012 /lib64/libssh2.so.1 -> /usr/openv/pdde/pdopensource/lib/libssh2.so.1.0.0*

rpm -qf /lib64/libssh2.so.1

file /lib64/libssh2.so.1 is not owned by any package

5. Delete the link:

rm /lib64/libssh2.so.1

6. Refresh the library links:

lddconfig

rcapache2 start

There was a wrong library link.
