Error: conversion error: error generating ACI: archive/tar: cannot encode header about docker2aci

[zhsj]

The previous comment is false, the error is still in appc/docker2aci

docker2aci/lib/internal/internal.go

Line 629 in 365911f

t.Header.Linkname = path.Join("rootfs", t.Linkname())

Here, the len(Linkname) > 100, making the t.Header.Format which is USTAR invalid.

How did you build this docker2aci binary? I'm starting to suspect that this is a regression in Go 1.10. If I try with the binary attached to the github release or with one locally built with go-1.9, I can't seem to reproduce this.

@lucab tried myself, and I can confirm the binary on github release is fine. And the one built by Go 1.10 failed.

The build method is nothing special, just go build.

Thanks for confirming, that's also the behavior I see with a local go-1.10 build. I reported the regression to golang/go#24821, and I'd be happier if this turns out to be directly fixed in archive/tar.
