Hmm looks like on apt package update you get redirected to an Armbian mirror mia-mirror.bret.dk that did not exist or has issues.

Could you try following

apt update
apt upgrade

Here’s what it shows:

oot@DietPi:~# apt update

E: dpkg was interrupted, you must manually run ‘dpkg --configure -a’ to correct the problem.

I did

dpkg --configure -a

Then apt update & apt upgrade
then dietpi-update and it works this time.

For anyone who has similar problems.
