if by fresh install you mean nuking the old partitions and installing brand new 13.0 from an usb stick no, this is not a fresh install, fresh as in just now installed
I am running trixie
in /etc/apt/sources.list.d there is only one txt file named debian.sources, as explained in debian's instructions page. Is that wyat you mean?
I also updated grub after freeing some boot space: sudo update-grub2
thanks. I did all that. Is it safe to reboot? don't want to ruin the machine
