Troubles when apt-update and apt-upgrade

I’m trying to upgrade ubuntu by

sudo apt-get update && sudo apt-get upgrade

But there is the error due upgrading (only tail of logs):

Unpacking libpython3.6-minimal:arm64 (3.6.9-1~18.04ubuntu1.7) over (3.6.9-1~18.04ubuntu1.4) ...

Errors were encountered while processing:

So how I can handle with this problem?

Looks like you manually installed bluez before and it failed and affect the apt status?

No, I didn’t install anything by hand

sudo dpkg --remove --force-remove-reinstreq package_name

Try to use above command to remove your 12-bluez-obexd_5.48-0ubuntu3.8_arm64.deb?
