Eroor when updating the software packages in Ubuntu 20.04

Options

I am using Teamviewer for Linux version 15.14.5. I am using Ubuntu 20.04 as my operating system. After upgrading to Ubuntu 20.04, I get the following error message when trying to update the software packages for Teamviewer:  

"Failed to fetch https://linux.teamviewer.com/deb/dists/development/InRelease 403 Forbidden [IP: 2600:9000:20c3:2200:1c:3aaa:b100:93a1 443]

E: The "https://linux.teamviewer.com/deb development InRelease" depot is not signed.

N: Updating from such a depot cannot be done in a secure way, so it is disabled by default."

Is there any solution for this problem? Any help apreciated.
