Comment 2 for bug 1960582

To clarify this : i didn't make any change to the system.
I just upgraded from ubuntu 20.04 and get that error.
Step to reproduce :
-in Ubuntu version 20.04
 $ sudo apt update
 $ sudo apt upgrade -> (no error)
 $ sudo apt dist-upgrade
 sudo apt autoremove
 sudo apt install update-manager-core
 sudo do-release-upgrade -d
 after upgrade
-in Ubuntu version 22.04
 sudo apt update
 sudo apt upgrade -> show above error
so please verify whether it's a bug from upgrade older version to jammy
thank you,
