Key is stored in legacy trusted.gpg keyring

[Krispy234]

Hello,
When I try to install RPi-Monitor on Raspberry Pi OS - Bookworm I receive a warning message after I run the command sudo apt-get update.

I get the following message:
W: http://giteduberger.fr/rpimonitor/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

Is it possible to solve this from my side?

Thanks for the help.

I had the same issue this fixed it:

sudo apt-key del 2C0D3C0F
gpg --keyserver keyserver.ubuntu.com --recv-keys E4E362DE2C0D3C0F
gpg --export E4E362DE2C0D3C0F | sudo gpg --dearmor -o /usr/share/keyrings/rpimonitor.gpg
echo "deb [signed-by=/usr/share/keyrings/rpimonitor.gpg] http://giteduberger.fr rpimonitor/" | sudo tee /etc/apt/sources.list.d/rpimonitor.list > /dev/null
