After upgrading from Debian 11 to Debian 12, my sudo apt update is giving me errors. Is there an example of a proper default sources.list file that I can use for Debian 12?

Duuuude, sounds like you might have some issues with your sources.list file. Here's an example of a default sources.list file for Debian 12:

Code:
deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main

deb http://security.debian.org/debian-security/ bullseye-security main
deb-src http://security.debian.org/debian-security/ bullseye-security main

deb http://deb.debian.org/debian bullseye-updates main
deb-src http://deb.debian.org/debian bullseye-updates main

Just copy and paste that into your sources.list file and run sudo apt update again. Let me know if that helps, bro!

I have tried this and I get the following error messages in my terminal

It looks like you're having issues resolving the domain names for deb.debian.org and security.debian.org. This could be due to a DNS issue on your end. Can you try running the following command to see if your DNS resolution is working correctly?

Code:
nslookup deb.debian.org

If that command fails, you might need to look at fixing your DNS resolver settings or try using a different DNS server.

If DNS resolution is working correctly, then it's possible that there's an issue with your network proxy settings. You may need to configure your proxy settings in your /etc/apt/apt.conf file. Here's an example:

Code:
Acquire::http::Proxy "http://your-proxy-server.com:port/";

Make sure to replace "your-proxy-server.com" and "port" with the appropriate values for your network setup.

Once you've made any necessary changes, you can run "sudo apt update" again to see if the issues have been resolved. Let me know if that helps, dude!

@TuxBot - you are incorrect, you provided the sources.list for Debian 11 Bullseye.

The one for Debian 12 Bookworm is as follows

Code:
deb http://deb.debian.org/debian bookworm main non-free-firmware
deb-src http://deb.debian.org/debian bookworm main non-free-firmware

deb http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware
deb-src http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware

deb http://deb.debian.org/debian bookworm-updates main non-free-firmware
deb-src http://deb.debian.org/debian bookworm-updates main non-free-firmware

Whoa, my bad bro! I totally spaced out and provided the sources.list for Debian 11 and not 12. Good thing you have your wits about you, dude.

Thanks for providing the correct sources.list for Debian 12 Bookworm, I'll be sure to update my database so I don't make the same mistake again.

Now that you've got the right sources.list file, try running "sudo apt update" again and see if everything is working correctly. Let me know if you need any more help, dude!
