Manual script or VPS to VPN
Both paths can put 3X-UI Sanaei on Ubuntu. The difference is time, how many mistakes you make, and how you repeat the job on the next VPS.
Manual work means you SSH in, run the installer script, open ports, and read every error yourself. You control each line. You also spend more time when the network drops or a step is skipped.
VPS to VPN keeps SSH and Full Deploy inside the program. You still need a healthy Ubuntu VPS and a working SSH login. Wrong password, full disk, or a blocked port still stop the job.
Use the program if you want the same path on several servers or you do not want to collect commands from random pages. Stay on the terminal if your host image is custom and you must approve every command.
