Error when up the machine on the VirtualBox

Please, I need some help with an issue

I have a virtual machine that runs a legacy system that we need to keep ubuntu 12.

But this system is deprecated and the libs are unaccessible.

I destroyed the machine and update VirtualBox, now when I try up the machine appears a message:

[default] GuestAdditions versions on your host (6.1.34) and guest (4.2.0) do not match.

So I see that before starting provision, the system try install some packages:

fakeroot linux-headers-3.2.0-23 make patch

But it can’t because repositories are inaccessible. Then it can’t do mount and provision.

In the end, happens the following error.

Stdout from the command: umount /mnt

PS: I upgraded the VirtualBox because occurs an issue that I needed to restart the hosts all the time to do a provision

Some informations:
VirtualBox Version: 6.1.34
Vagrant Version: 2.2.19
Guest Additions Version: 4.2.0
