@ruzickap, thanks for opening, and sorry to hear that, what happens if you remove the iso_checksum_type part ?

ruzickap · 2020-02-21T10:55:05Z

Let me try it using these commands:

cat > bug.json << EOF
{
  "builders": [
    {
      "vm_name": "test",
      "type": "qemu",
      "ssh_username": "root",

      "iso_urls": "http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/installer-amd64/current/images/netboot/mini.iso"
    }
  ]
}
EOF

wget https://releases.hashicorp.com/packer/1.5.4/packer_1.5.4_linux_amd64.zip

unzip packer_1.5.4_linux_amd64.zip

./packer validate ./bug.json

Output:

Template validation failed. Errors are shown below.

When using "older" packer it's fine:

$ packer --version
1.5.1

$ packer validate ./bug.json
Template validated successfully.

Welp, this sounds like a bug and we will investigate !

ruzickap · 2020-03-13T12:28:57Z

Ok.
Thanks s lot for looking at it...

sylviamoss · 2020-03-23T10:22:28Z

Closed by #8897
This will be on 1.5.5 release :)

ruzickap · 2020-03-26T09:52:32Z

Hello.

Thanks a lot for fixing it...

It looks like this issue was partially fixed. The example above, when I'm using the iso_checksum_url as https://..., was fixed :-)

But if I use iso_checksum_url pointing to local file as described in the Packer documentation (https://packer.io/docs/builders/qemu.html#iso-configuration) - it is not working:

wget -c http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/installer-amd64/current/images/SHA256SUMS
cat > bug.json << EOF
{
  "builders": [
    {
      "vm_name": "test",
      "type": "qemu",
      "ssh_username": "root",
      "iso_checksum_url": "./SHA256SUMS",
      "iso_urls": "http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/installer-amd64/current/images/netboot/mini.iso"
    }
  ]
}
EOF

wget -c https://releases.hashicorp.com/packer/1.5.5/packer_1.5.5_linux_amd64.zip

unzip packer_1.5.5_linux_amd64.zip
