解決辦法

進入/etc/apt/sources.list.d檔案把有關python3.6檔案，以list結尾的檔案刪除。或者修改為.bak結尾

root@iZuf6b77csetgh3jg7sw2tZ:~# cd /etc/apt/sources.list.d
root@iZuf6b77csetgh3jg7sw2tZ:/etc/apt/sources.list.d# ls
deadsnakes-ubuntu-ppa-focal.list deadsnakes-ubuntu-ppa-focal.list.save jonathonf-ubuntu-python-3_6-focal.list jonathonf-ubuntu-python-3_6-focal.list.save
root@iZuf6b77csetgh3jg7sw2tZ:/etc/apt/sources.list.d# sudo mv jonathonf-ubuntu-python-3_6-focal.list jonathonf-ubuntu-python-3_6-xenial.list.bak
root@iZuf6b77csetgh3jg7sw2tZ:/etc/apt/sources.list.d# ls
deadsnakes-ubuntu-ppa-focal.list deadsnakes-ubuntu-ppa-focal.list.save jonathonf-ubuntu-python-3_6-focal.list.save jonathonf-ubuntu-python-3_6-xenial.list.bak
root@iZuf6b77csetgh3jg7sw2tZ:/etc/apt/sources.list.d# sudo mv deadsnakes-ubuntu-ppa-focal.list deadsnakes-ubuntu-ppa-focal.list.bak

在進行

sudo apt-get update

root@iZuf6b77csetgh3jg7sw2tZ:/etc/apt/sources.list.d# cd ~
root@iZuf6b77csetgh3jg7sw2tZ:~# sudo apt-get update
