Debian 8 install hangs at 'apt-get install && apt-get upgrade -y'

[wzzrd]

After the package upgrade step for Debian 8, vagrant-builder / virt-builder hangs with the output below (added -v -x to the virt-builder commandline):

commandrvf: /bin/sh -c "exec >>'/tmp/builder.log' 2>&1

This is with unedited vagrant-builder files.

So this shitty thing about vagrant-builder is that unrelated "families" (whatever that means) have essentially different copies of the same code, since I was either too lazy or didn't care, or it was too hard, to unify one "code base". So the stuff you just patched (the raw vs qcow2 thing) happened in the v7/ folder, where as everything in debian/ is separate. So perhaps you have the same issue, and I forgot to ask you to patch it in both places.

So 1) try that same fix. 2) Please submit another patch

3. Feel free to try and unify the two code bases, although that's an optional goal
4. I realized that the last images I built were actually made on Fedora 21. So indeed I am now on F23, but perhaps I might not have tested the code fully with these new versions.

I tried the same fix already. Will look into this later. Not a real high priority for me :)
