chmod command only works on files and directories that you have the permission to modify. If you do not have the necessary permissions, you will need to use the sudo command to run the chmod command with superuser/root user privileges.
You will be prompted to enter your password to authenticate as the root user.
If you do not have admin privileges, only way to achieve this is to request for it from your admin or ask them to update the write permissions on the disk.
Hope that helps.
If you have further questions, do let me know in the comments and I will be happy to investigate further.
I don't have admin right to do that. Do you know what i can do it?
What do you expect as answer? Do you want us to help you crack someone else system?!?
If you don't have admin permission the speak with the admin.
If you are the owner of the Azure subscription then you can change the admin password if needed. You can also send command from the Azure portal. For more information on doing this, check the following doc:
