Failed to fetch

All of my Systems which are running DietPi throw the following exception on apt-get update.
Is this related to the Debian 10 “Buster” release?

Try again later…the repo might be down…or have heavy load

I run on the same issue on a brand new Odroid N2 setup yesterday - it seems was down (it is up again now).
To overcome, the following worked for me:
Change with in /etc/apt/sources.list.d/meveric.list* and it should work again.

The following sed statement did the trick :

# sed -i -e 's/http:\/\/\/meveric/https:\/\/\/meveric/' /etc/apt/sources.list.d/meveric-*.list
