I'm using Fedora 27 with Linux 4.14.16-300. Every time I reboot it gives me an error:
License checkout failed.
License Manager Error -9
The hostid of your computer ("8e16dd22f151 d050993b4804") does not match the hostid of the license
To run MATLAB on this computer, you must run the Activation client to reactivate your license.
Troubleshoot this issue by visiting:
License path: /home/josh/.matlab/R2016b_licenses:/usr/local/MATLAB/R2016b/licenses/license.dat:/usr/local/MATLAB/R
Licensing error: -9,57.
Something must be reset after each reboot, but I can't figure out what it is. The hostid is just the MAC address of my wireless adapter, followed by that of my ethernet adapter, neither of which should change on reboot. I'm not sure why the license file looks for a single hostid either, rather than a double one like my computer has. Has anyone else run into this issue? This is with MATLAB R2016b.
EDIT: After a reboot I have realized that my network adapters' MAC addresses are randomized on each boot. I believe setting a static MAC address (if that's possible on Fedora) will solve this problem. It's probably bad practice to link a license to something that the operating system changes by default.
