I'm on an Arch-based Linux with VirtualBox (generic installer, couldn't load modules with host-modules-arch) and I get this error whenever I try to import this OVA file:
Error reading OVA '.../coa-aio-newton.ova' (VERR_TAR_UNEXPECTED_EOS)
Result Code:
VBOX_E_IPRT_ERROR (0X80BB0005)
Component:
ApplianceWrap
Interface:
IAppliance {86a98347-7619-41aa-aece-b21ac5c1a7e6}
Apparently, these OVA files should be unpackable but tar doesn't recognize it, and neither Ark or PeaZip can unzip this, but importing this OVA file works on Win 10.
I've tried using VMWare but that gave me an import error too. Why can't virtualization work at all on Arch-based systems?
It looks like typical M$ EEE strategy, stage 2: extend standard to break compatibility. But OVA images produced by different virtualization systems are almost always incompatible to each other on the level of xml metadata. Seems that just one more level of incompatibility was added in archive format.
"UNEXPECTED_EOS" is almost certainly "unexpected end of stream", that is, the file is missing the end or there's data corruption and the unpacker has interpreted the bad data as meaning the file should be longer than it is.
Redownload the file, or try to download it using a different tool (e.g. wget or curl rather than a browser). If that still gets a truncated file, try a different source / mirror.
