Cannot start license manager in Ubuntu

I’m following this page to install license manager on Ubuntu,

But I met some errors when starting the license manager using lmstart:

14:15:47 (lmdown) [MathWorks] process id = 32186 . . . (lmgrd) - killed

14:15:49 (lmgrd) MLM daemon found no features. Please correct

14:15:49 (lmgrd) license file and re-start daemons.

14:15:49 (lmgrd)

14:15:49 (lmgrd) This may be due to the fact that you are using

14:15:49 (lmgrd) a different license file from the one you expect.

14:15:49 (lmgrd) Check to make sure that:

14:15:49 (lmgrd) /var/tmp/lm_TMW.dat

14:15:49 (lmgrd) is the license file you want to use.

14:15:49 (lmgrd)

My whole steps:

1. Download license file from license center, entered hostid, login name, etc

2. Install license manager and get a ‘hostid not found’ warning

3. Manually add a SERVER line to license file and dismissed the warning, successfully get license manager installed

4. Run lmstart after installation

Environment:

Ubuntu 20.04 LTS

Is MATLAB installed? No
