Why am I unable to start the network license manager, or use license manager utilities on Linux.
When I try to do so, may receive an error such as:
ERROR: ./lmgrd: Command not found.
OR
ERROR: /lib64/ld-lsb-x86-64.so.3: bad ELF interpreter: No such file or directory
OR

One or more of these errors will occur if you try to run the License Manager on a system which is missing the Linux Standard Base (LSB) library, which the License Manager is dependent upon. 
The workaround is to have the License Manager use a standard library by adding a symlink to your operating system.
To add the the symlink, navigate to the /lib64 directory and run the following command:
ln -s ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3
Once you have added the symlink, verify it by running the following:
ls -l /lib64 | grep lsb
The output should be:
lrwxrwxrwx  1 root root   20 Jan 12 18:58 ld-lsb-x86-64.so.3 -> ld-linux-x86-64.so.2*
With the symlink in place, retry starting the License Manager.
