Why do I have "License checkout failed" problem on MATLAB 2017b on Ubuntu 17.10 after I activate MATLAB?

I have same error every time when I tried to run MATLAB.

License checkout failed.
License Manager Error -8
Make sure the HostID of the license file matches this machine, and that the HostID on the SERVER
line matches the HostID of the license file.
