Error while compiling qubes-vm

Getting close to getting everything to build. I’m just getting some build errors, which I don’t understand where they’re coming from. Do I need to run make with sudo?

It mean:

So what is your build environment and can you build in a difference environment (use a difference OS)

I’m using Fedora 33. I’m trying to compile Whonix after the qubes-vm. Not using a disposable VM till minimize configuration variables for now. Should I be using Debian for this? If I delete the Qube does that clear the used disk space?

That’s something I’ve seen myself. Other symptoms include script refusing to run, screen refusing to open a new window, you name it.

I don’t have a full diagnostic for now, but the following are probably relevant:

  • qubes-builder creates bind-mounts of several dirs into its chroots (here /dev/pts is relevant, but you’ll see /proc and others)
  • in some situations after a run those mounts are not cleaned up (could not see a pattern, eg. this happened to be both on build success and build failure)
  • as a result I ran into errors when carelessly attempting to sudo rm -rf the chroots: obviously we must cleanup the mess first


  • I don’t see why the unmounting of bind-mounts would end up unmounting /dev/pts
  • you did not mention going such a route, so I tend to assume you did not :slight_smile:

So we most likely have a bug in bind-mount handling (at least for the ones not getting unmounted), and this might be related (eg. could be unmounting the source of the bind-mount instead of the target).

Should I be using a Debian OS for building Whonix?

that weird

maybe you should try

Debian breaks the dependencies needed for pulling everything in. Getting the same errors just starting with the setup script, and a fresh qube. I’m using an Insurgo laptop.

Following this with updated values.
