error while installing stratux fresh. about stratux HOT 4 CLOSED

this is also reproducible when running make optinstall

You need root permissions to write /opt. Can't do that as a normal user.

I thought running it as Sudo took care of that ? also the folders and the files already exist under stratux/www/css.

You ran "make" with sudo, but not "make install" or "stxrestart"

sorry, this is not an "introduction to the Linux shell" support forum. This will be the least of the issues you will be facing.
If you want something that works much simpler and much more reliable, use a Stratux base image and start from there. All the heavy lifting is done there. See https://github.com/b3nn0/stratux/blob/master/image/mk_europe_edition_device_setup64.sh
