fix fetch and checksum error on new packer

[BenGardiner]

(but still won't build for me)

this might be good enough for the minimum changes requested in #45

[bastibl]

This seems to get us one step further. I tried several hours to get the base installation going to no avail. I don't even know if the problem is packer, virtualbox, or subiquity... I tried several combinations of workarounds but no chance :-/

[BenGardiner]

thanks for letting me know @bastibl -- it helps alot to know the problem isn't necessarily on my end !

I've done a bunch of attempts here. Including moving the packer json to a vagrant file and starting with generic/ubutunXX

vagrant version has the advantage that I can pass the ssh step but all ubuntu versions I tried fails with checksum mismatches.

now both packer builds work when invoked via make on updated and upgraded 21.10 ubuntu machine:

Great! Looks like all dependencies are installed. You can go ahead and type 'make' to build the VM.

This is strange. I also have an up-to-date Ubuntu 21.10 system and tested with the packer from the main repo and a more recent version from their PPA. Virtualbox is the same. For me, it hangs during subiquity installation when it tries to download and apply security updates. Do you have any ideas?

[bastibl]

Looks like something timed-out after >30min and the build continued. Then got another bug with the more recent packer version. After downgrading it worked. What a SW ecosystem :-) Thank you for the PR!
