Unable to resolve host error when using sudo in Debian WSL

I was trying to update my packages sudo apt update; sudo apt upgrade on a newly created WSL Debian instance but all of the requests to get new repositories failed with this error.

sudo: unable to resolve host Desktop-Dell: Temporary failure in name resolution

Afterwards, apt returned Failed to fetch I am using a Inspiron 16 Plus 7630 and installing Debian 12 Bookworm I installed Debian by running wsl --install -d Debian I tried modifying /etc/hosts and /etc/hostnames (I used nano to modify the files) to include my computer's hostname but instead it triggered the safe mode of WSL which disabled some features but I was still getting the same error as before. I also tried reinstalling WSL and Debian but nothing worked. /etc/hosts

127.0.1.1    Desktop-Dell

/etc/hostname

DESKTOP-DELL

I followed online guides to change these two files and reboot to resolve the host. [AskUbuntu](https://askubuntu.com/questions/59458/error-message-sudo-unable-to-resolve-host-none) **I can't update my apt repositories or access the internet. What steps could I take to resolve the host and fix the internet problem? Is this a problem with the naming of the hostname or is it a problem which requires a system reinstall or a problem with WSL and not with Debian?**
