Excessive, unnecessary output in command window

I am running the student version of R2018b on Ubuntu 18.04. My command window is displaying in red text a lot of information regarding HTTP data, and it's interfering with my ability to perform commands, as every command I put into the command window is followed by a wall of red text. An example includes:

03:46:49 INFO: READ:  OnHeadersReceivedMessage{type=OnHeadersReceived, uid=794, browserContextId=0, requestId=83, url=https://localhost:31515/messageservice/async, method=POST, originalHeaders=Date: Sun, 27 Jan 2019 20:45:49 GMT

And that's not even all that appears just from trying to show the value of a variable. Any idea of how to disable or get rid of this?

Answer 2

[Zaigham Randhawa]

I am literally facing the same issue. I am running Linux mint and I think am using the student version as well.

Did you figure the probem out?

Answer 3

[Friedrich Mangelsdorf]

I had the same problem and solved it.

The problem: I installed Matlab as root but my academic license is registrated on my normal username.

Solution: Just change the ownership of the Matlab folder and files from root to your username.

sudo chown -R username:group path_to_your_matlab_directory

I tried this but unfortunately it does not work :(
