The hypervisor is IPv6 capable and the URL is reachable over IPv6 as well, but the hypervisor / KVM Agent fails to download it.

    That is set to True already in the Agent, so it should use IPv6 as well.

    packer-templates.o.auroraobjects.eu is an alias for o.auroraobjects.eu.
o.auroraobjects.eu has address 185.107.215.161
o.auroraobjects.eu has IPv6 address 2a05:1500:ff01:7::161

    The host can reach the URL without any problems, but it is the Agent which seems to prefer IPv4 over IPv6.

    No, this is not resolved and still on the todo.

    It's on the internal todo of PCextreme as well.

    @sureshanaparti @nvazquez @wido I opened PR #5826 proposing a fix.
    It is as basic as removing the conditional on the UriUtils.validateUrl which throws an exception in the case of IPv6.
    That code is 10 years old, in "another era" where there was not much IPv6 support.

    Nowadays most of the repositories support both IPv4 and IPv6. Including the CloudStack repository, which triggered my main interest in fixing it as soon as possible when I was not able to install the System VM template from the download.cloudstack.org on an IPv6 CloudStack Zone.
