Why am I unable to start the Network License Manager on Linux?

Why do I receive one of the following errors when I try to launch the Network License Manager on Linux?

./lmgrd: Command not found.

           Your local lmhostid(s) are:

Please stop, fix the problem, and try again . . .

If you are using a version of the Network License Manager that shipped with R2024a or older, it required LSB on Linux to be installed. If LSB is not installed or unavailable on your Linux distribution, then errors above would appear.

You can fix these errors by replacing your existing copy of the Network License Manager with a version of the Network License Manager that comes with R2024b or newer. The latest version of the license manager can be installed using the R2024b MathWorks Product Installer or by downloading the binaries the ZIP archive found here:

The first version of lmgrd and MLM that MATLAB ships with that does not require LSB is v11.19.5.0. To check the version of lmgrd and MLM that you have already installed, use these commands in the directory that lmgrd and MLM live in.

./lmutil lmver lmgrd
./MLM lmver

 

Note: As of R2024b, the Enterprise License Manager binaries have similarly been updated to FlexNet v11.19.5 and no longer depend on the LSB Core libraries. However, these binaries are different and they can only be downloaded by a license administrator of an Enterprise license.
