debian power powerpc netinstall bad archive mirror
 

do I have to change my dns settings?

Hello and welcome to LQ!

It is impossible for us to answer that question, since you gave us no information that we can work with.

- Which version of Debian is this?
- What is the content of /etc/apt/sources.list?
- When exactly do you get that error?
- Have you tried a different mirror?
- Why do you think this might be a DNS issue?
