Facing issue when I'm try to install cursor in Linux

getting below error while I’m trying to install in Linux

/tmp/.mount_cursoroDLlGm/cursor: /usr/lib/x86_64-linux-gnu/libnss3.so: version `NSS_3.30’ not found (required by /tmp/.mount_cursoroDLlGm/cursor)

Maybe you need to update the libnss3 package on your Linux system.

Try these Terminal commands:
sudo apt update
sudo apt-get install libnss3

after this command, it show:
libnss3 is already the newest version (2:3.28.4-0ubuntu0.16.04.14).
