No HostID specified in license file
Answered
I recently set up my academic license, installed Gurobi, and ran grbgetkey with the key provided to me. I was able to successfully run the block of code in my Jupyter notebook that imported gurobi, but when actually using it (gp.Model) I encountered a "No HostID specified in license file" error.
I have a PopOS (Ubuntu-derivative) laptop on 20.04. I have installed gurobi in the default directory and have retrieved and activated my license. The error also appears when I run gurobi.sh. Any help would be appreciated.

Hi Bryan,
We had an issue with our license servers earlier today. If you have just installed your license, the license file may have been corrupted. Can you please try re-running the `grbgetkey` command to re-install your license?
