Hi ,

Did you solve it?

yes ,i have solved this error.

because i start the VncServer of Linux ,so default Port of VNC is 5901, so when sap installing, there need to assign the sap communication port with db2, the default also is 5901,so you can change it to another noused port.

after doing this, you will succeed your installation.
