If you are not the owner of a file you can't modify its permission bits. Well, with richacls you can do that, but you are not going to find it in a basic Ubuntu installation

The root user can do that. There are many ways to become root user in GNU/Linux. The recommended way to do this in Ubuntu is by using sudo

sudo chmod +x /opt/sqldeveloper.sh

The command to use is:

sudo chmod +x /opt/sqldeveloper.sh
