By going through the screenshot I think, apt is telling us that the following keys are missing 76F1A20FF897672F and 7373B12CCE03BEB4B. To add these keys, run the following commands:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 76F1A20FF897672F

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7373B12CCE03BEB4B

for more : go through this blog post

If you are facing errors still such as , no release file found and repository is not signed. Then you can try to remove those problematic PPAs. this blog post explains the process of removing those PPAs and run sudo apt update again
