NetBackup 8.2 and later RHEL 8 installation issue

After you provide the NetBackup license key during the NetBackup 8.2 and later installation on RHEL 8, you receive the error shown:

/usr/openv/netbackup/bin/admincmd/bpminlicense: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory (127)

This issue results from the upgrade of the libnsl.so.1 library by Red Hat. To resolve this installation issue, do one of the following:

  1. Before you start the NetBackup installation, log into the RHEL 8 server with root credentials and install the libnsl library.
  2. Log into the RHEL 8 server with root credentials and install the libnsl library. Then reinstall NetBackup.
