Unable to install : bad header in repo

[toxic0berliner]

Hello,

I had a working install of ubuntu and virtualbox.
After several updates of chrome os without using my chroot, I needed to use my windows vm today.
I did the change-kernel flags thing in crosh
I then tried the setup thing in the chroot
and that's where it fails : apt-get update is not working...

As of now, I'm still unable to start my existing VM since virtualbox complans about the drivers.

Thank you in advance for your kind help !

My guess is that something is wrong around here :

Also, for completeness, here is the content of my /etc/apt/sources.list.d/crouton-packages.list :
