This APT repository has been removed: /repositories/home:/pragmalin - openSUSE Download

Debian 10 means Debian Buster, but your other lists show that you are using Bookworm, 2 versions newer. Try this:

sed -i 's/Debian_10/Debian_12/' /etc/apt/sources.list.d/*.list

Then dietpi-update should work again.

Is there a particular reason you added this repository? It seems to provide rpi-imager only, but a very outdated version. Latest is v1.9.4, while the repo ships v1.7.5. If you use the Raspberry Pi Imager, better download a recent package from RPi website:

cd /tmp
wget https://downloads.raspberrypi.org/imager/imager_latest_amd64.deb
apt install ./imager_latest_amd64.deb

So unless there is another good reason to keep that repo, I would just remove it:

grep -r pragmalin /etc/apt/sources.list.d

This print the file which contains the repo. Just remove it. There should be a related key as well, either in /etc/apt/trusted.gpg.d, or /etc/apt/trusted.gpg itself. Since you otherwise use Debian and DietPi repos only, you can remove /etc/apt/trusted.gpg in any case, if it exists.
