Installer issue on Linux Mint (ubuntu based distro)

Linux Mint 20.3
Kernel: 5.4.0-120-generic
Cinnamon version: 5.2.7

For the installer packages for Linux I am not able to install a Temurin version 8 JDK
One step 3 for the "Configure the Eclipse Adoptium apt repository:" I am met with permission denied
even using sudo doesn't help for that command

it shows the following:
tee: /etc/apt/sources.list.d/adoptium.list: Permission denied
deb [signed-by=/usr/share/keyrings/adoptium.asc] https://packages.adoptium.net/artifactory/deb una main

I needed a version 8 for Ren'py

Start by reproducing the Linux Mint 20.3 failure at step 3, “Configure the Eclipse Adoptium apt repository,” and inspect the installer command that writes adoptium.list. Done means the repository configuration completes without the reported permission-denied error and allows Temurin 8 to be installed.
