I download gurobi on linux(ubuntu 20.04) and follow the installation guide to modify the environment variables, and I got the license.

After that, I run "gurobi.sh" in my terminal, but it keeps telling me that 

$ gurobi.sh 
Python 3.7.14 (default, Sep 15 2022, 10:56:34) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux
Type "help", "copyright", "credits" or "license" for more information.
Set parameter LogFile to value "gurobi.log"

Maintenance expired 1970-01-01, release built 2023-01-25

 

I have checked the whole installing process many times and I have re-installed gurobi twice, but the problem still exits.Could you please tell me how to solve it? I am sincerely grateful for your help!

  Hi Mian,

  Could it be that the date and time on your machine is not synchronized?
  Do you already have created a license file in the Gurobi Portal?

  Best regards,
  Mario

  Thanks for your advice!

  I have checked the time and date on my machine and it's right.

  And there is no license file in my Gurobi Portal, but I got a free academic license.

  I just missed a point that there is a “MAINTEXPIRATION=1970-01-01” in my gurobi.lic. Before seeing your comment, I asked the technical staff and he/she told me to re-apply a new license. 

  As I'm writing this, I've received a new license. I am gonna try it.

  Thank you.

  This line should definitely not appear in your license file. I guess with a correct license file you should be fine.

  I really appreciate your help.🫡

  With the new license, the problem is solved.

  I can't believe such a problem has been bothering me all day.😓

  Hello! I am actually having the same problem - and it has been going on for day. I installed gurobi SEVERAL times and still got the issue. I even tried with a new license. Just to be clear, I am using a free trial one. 
  
  Thanks for tour help!

  Hi Allegra,

  I just checked your license file in the Gurobi Portal, and it looks correct.
  Are you saying that you get a "Maintenance expired 1970-01-01 ..." error message?

  Best regards,
  Mario
