Cannot install new os

[FauzanNaim]

It states that there is no space to install the new OS but i did remove all unnecessary .pkg. Supposedly, if the switches are stacked, only the main have the OS right? And help me identify the N file. Thank you

Try 16.12.8 is the suggested version.

use below guide :

Regarding N - when you copied you might have copied as N, you can delete that file.
