vagrant box contrib-buster64 10.7.0 gets stuck on unattended upgrade

[Gerard Borst <gerard.borst@argosnotary.com>]

Hi,

The vagrant box https://app.vagrantup.com/debian/boxes/contrib-buster64/versions/10.7.0 gets stuck during provisioning with upgrade.

It is running into the upgrade of grub-pc https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1790923.html

Is it possible to upgrade the box to 10.8.0?

If you point to the source I maybe can make a PR myself.

Met vriendelijke groet,

Gerard Borst
