Thanks for your report.
Just to clarify:
- You installed fresh Debian image successfully and it works well, allowing APT upgrades and other web access without DNS errors?
- Then you ran DietPi-PREP to install DietPi on it?
- While DietPi-PREP is running you face DNS resolve errors, e.g. during the APT steps done within the script?
- Or did the DNS errors appear after the script has successfully finished and reboot done?
