ServiceDeskPlus on Ubuntu 21

ServiceDeskPlus on Ubuntu 21

Hi,
I have downloaded the ManageEngine_ServiceDesk_Plus_64bit.bin and trying to install it on Ubuntu 21, 64-bit system.
here is what i have tried;
1 sudo chmod +x ManageEngine_ServiceDesk_Plus_64bit.bin
2 ./ManageEngine_ServiceDesk_Plus_64bit.bin and then followed the on-Screen instructions.
The installer asked for the web-port and I entered 8585
Next couple of screens, i got the message DB started successfully.
Next couple of screens, The installer says - Installation successfull.

And then, I navigate to - /home/mahesh/maney/service-desk-plus/ServiceDesk/bin and execute ./run.sh
I get the following error message

When i navigate to /home/mahesh/maney/service-desk-plus/ServiceDesk/pgsql/bin and try to execute
psql -U postgres -p 65432 -d servicedesk

I get the following error
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.65432" failed: No such file or directory
    Is the server running locally and accepting connections on that socket?


Can you help me with installation and starting Service Desk Plus ?
