Troubleshooting

Hello,

Trying to run dietpi-update to update to 8.18.2 from 8.17.2 and it fails and give the following error, something about the repos not being secure.

Maybe it needs to be removed but no idea where this is held.

Thanks.

So I went into /etc/apt/sources.list.d

and renamed debian-backports.list to debian-backports.list.old and then ran dietpi-update and this time it updated fine.

is this Repo important or can i just ignore this one. thanks

You are using an old Debian Buster system. And we don’t offer these images anymore for 2 years. Therefore, the source file must have been created manually later. Anyway, http://httpredir.debian.org/ is not the best option for Debian packages. You should rather use http://deb.debian.org/.

Additionally, you are using an old image based on Raspbian OS. Therefore, it is quite possible that the Debian package source no longer contains a valid PGP key. This would then have to be updated.

However, it would be better to upgrade to Debian Bullseye. DietPi - How to upgrade to "Bullseye" - DietPi blog
