My OS version is 5.1.7 Hera. I got the following error when I try to update in app center:

I tried sudo-apt-update, sudo-apt-upgrade, sudo-apt-autoremove, but still error.
I also tried apt-get clean, rm -rf /var/lib/apt/lists/*, apt-get clean, apt-get update, apt-get upgrade, but still got error.
I don't understand how to fix it. Any help will be appreciated. Thank you.
