I am running this inside an Ubuntu VirtualBox with a Windows host

The relevant error is:

losetup: cannot find an unused loop device

Can you list the loop devices inside your vm ?

sudo losetup -a

If there is none, can you ensure the kernel module is enabled ?

sudo modprobe loop

Ah... you have to use sudo to build the image...

[geneoes]

Ah... you have to use sudo to build the image...

Ahh right!
I didn't because when using sudo: sudo: d2vm: command not found
I installed it through brew install linka-cloud/tap/d2vm

[Adphi]

I always forget... since ubuntu 20.04 the user's $PATH is not preserved by sudo, so you need to run with the -E flag:

sudo -E d2vm ...

[geneoes]

hey yeah I tried but same message

sudo: d2vm: command not found

[Adphi]

what is the output of which d2vm ?

[geneoes]

what is the output of which d2vm ?

/home/linuxbrew/.linuxbrew/bin/d2vm

[Adphi]

can you show me your $PATH ?

echo $PATH

[geneoes]

/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin

[Adphi]

Can you try sudo env "PATH=$PATH" d2vm ... ?

[geneoes]

That worked and the build finished successfully, thank you!

[Adphi]

You're welcome !
