Re-running vagrant up gives

    Bringing machine 'default' up with 'virtualbox' provider...
    ==> default: Checking if box 'debian/bookworm64' version '12.20240212.1' is up to date...

    ==> default: Machine 'default' has a post `vagrant up` message. This is a message
    ==> default: from the creator of the Vagrantfile, and not from Vagrant itself:
    ==> default: 
    ==> default: Vanilla Debian box. See https://app.vagrantup.com/debian for help and bug reports

almost immediately. Looks like timing out was not the real issue. I can run vagrant ssh now.

Realizing there's no cc and no git, I try

    $ apt-get update
    Reading package lists... Done
    E: List directory /var/lib/apt/lists/partial is missing. - Acquire (13: Permission denied)

Hmm, still some challenges ahead...

sudo apt-get update?

Ah, of course. Have not used Linux for so long, I forgot.

or just

sudo apt update
