Error in qubes-builder while making qubes-vm in order to build Ubuntu template

[yitjob]

Qubes OS version (e.g., R3.2):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

qubes-builder is installed in a standalone vm based on fedora-23, following the Arch Linux procedure.

---

Expected behavior:

Running ./setup and following pre and post instructions, should produce similar results to the guide written for Arch.

Actual behavior:

When doing the merge after getting all sources, several .tar.gz files of 0 bytes of size appear in the folder qubes-src/vmm-xen/, and this is probably ok for some of those files, but when running
make qubes-vm, the command qubes-src/vmm-xen/debian-quilt qubes-src/vmm-xen/series-debian-vm.conf /home/user/qubes-builder/chroot-xenial//home/user/qubes-src/vmm-xen/debian/patches tar xfz "/home/user/qubes-builder/chroot-xenial//home/user/qubes-src/vmm-xen/xen-4.6.6.tar.gz" -C /home/user/qubes-builder/chroot-xenial//home/user/qubes-src/vmm-xen/debian-vm --strip-components=1

raises an error and the build is interrupted.

Steps to reproduce the behavior:

[...]
[user@dev qubes-builder]$ make get-sources
[...]
[user@dev qubes-builder]$ make qubes-vm

General notes:

Related issues:

Btw, before this point, there appears to be an error related to dependencies, which I commented in the relevant issue (#3038).

[unman]

There are two problems here: First you're building with Fedora23 which is eol. The issue with dependencies wont arise if you use a newer Fedora and update your git.

The other problem is this:

several .tar.gz files of 0 bytes of size

This indicates that your download of some of the necessary files failed.

Can you try updating your build environment and running 'make get-sources' again.
I cant replicate this on a clean Fedora 25 build environment.
