It’s an easy enough mistake to make. I am pretty sure now that it will build successfully 🤞

Under Ubuntu he is still building …

At the same time on archlinux I get this error “cdrom”

```auto

looks like loop mounts (mounting a disk image file) are not allowed or you have a desktop environment with a strange automount feature.

That is not an inherent aspect of archlinux.

I use archlinux for my build system, runni g with an xfce4 desktop and I have never had that problem.
