How do I solve this sudo apt update error?

Err:9 http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04  InRelease
  The following signatures were invalid: EXPKEYSIG 23E07629B9E3C9E4 home:pzz OBS Project <home:pzz@build.opensuse.org>

W: Some index files failed to download. They have been ignored, or old ones used instead.

I have tried solutions from post How do I fix the GPG error "NO_PUBKEY"? but they did not work:

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 23E07629B9E3C9E4
[sudo] password for master: 
Executing: /tmp/apt-key-gpghome.QYq1pmnpyE/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 23E07629B9E3C9E4

You have added some thirdparty repository to the system. For now its key is expired.

So you have to disable this repository using Software & Updates.

Just update the expired gpg key:

curl -fsSL https://download.opensuse.org/repositories/home:pzz/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_pzz.gpg > /dev/null

My error was with Google Chrome, so I just updated it with:

wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo gpg --dearmor -o /usr/share/keyrings/google-chrome.gpg

Then updated with

sudo apt update

My issue was with Amazon Corretto, so I did this:

wget -O - https://apt.corretto.aws/corretto.key | sudo gpg --dearmor -o /usr/share/keyrings/corretto-keyring.gpg

then ran:

sudo apt update
