I cannot reproduce this issue on Debian Bullseye (amd64). I did however face the following issue: https://github.com/aleph-im/aleph-vm/issues/124

hoh commented 2 years ago

This was reported as a bug local to the developer's system.

I have reopened this issue due to the progress of the investigation.

Affect custom python script, shell scripts that are related to the Python environnement related #232 ?

The hostname of the vms exceeds 63 Characters as also descibed here => https://github.com/aleph-im/aleph-vm/blob/main/vm_supervisor/views.py#L47

and makes the vm crash
