Try running with following command :

sudo python install.py --production --user Your_USERNAME --mariadb-version 10.3 --verbose

Thank you Nikunj Patel
While running above command, I am getting this error
install.py: error: unrecognized arguments: --mariadb-version 10.3


Which install.py you are running ?

Please follow the instruction on the link below :

If you still face a problem we need to check in details of what is happening.

It seems the installation file you are running is not the correct. Did you check manually what if mariadb version if it was already installed on you pc.

To know the mariadb version follow methods on the link below :

Thank you Nikunj.
That mariadb version issue fiixed.

Now I am getting another error.

Are you working with local machine. Is it possible for you to give remote access via teamviewer13.

Because this can go on for ever…


I am working in AWS EC2

We can work in Teamviewer…


hi you have installed teamviewer16… so i cannot connect.

download teamviewer 13 from the link below.

I have licensed version 13 so i dont want to upgrade.

I am using ubuntu, I will try to install tv 13 and let you know

Thank you Nikunj_Patel for your help on installation process.
You have done a grate job.
