I recently upgrade from ubuntu 23.10 to 24.04 using the do-release-upgrade command. Everything went fine and the upgrade completed. However every time I do the apt update command I get this.

It doesn’t seem to affect the system but any help getting rid of this warning would be appreciated.
This is what “cat /etc/apt/sources.list.d/ubuntu.sources” outputs

So I found the solution. There is the file “third-party.sources” in “/etc/apt/sources.list.d” add “Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg” to the end of it.
Missing the signed key for third-party.sources
Doing this via ssh should fix it.
sudo nano /etc/apt/sources.list.d/third-party.sources
Then at the end of the file add this line.
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
Final file should look something like this.
Types: deb
URIs: http://mirrors.digitalocean.com/ubuntu/ Suites: noble noble-updates noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
