Ubuntu 22.04용 "진짜" VNC?

저는 RPi4b에서 Ubuntu 22.04를 실행하고 있습니다. Windows PC에서 무료 VNC-Connect를 사용합니다. 하지만 Ubuntu에 서버를 설치하는 방법을 모르겠습니다.

realvnc.com에서 Linux 설치 파일인 VNC-Server-7.0.0-Linux-x64.deb를 다운로드했습니다. 그런데 설치하려고 하면 오류가 발생합니다.

sudo apt install ./VNC-Server-7.0.0-Linux-x64.deb

Note, selecting 'realvnc-vnc-server:amd64' instead of './VNC-Server-7.0.0-Linux-x64.deb'
