FUSE permissions can be enabled from within the management portal, select 'VPS Configuration' then within the Menu select 'Enable Fuse in Container'.
Once permissions have been updated please ensure the VPS has been Stopped and then Started from within the Management Portal to allow the configuration to be applied.
Restarting the VM from within the instance e.g. 'shutdown -r 0' will not apply the required configuration changes on the hypervisor.
You can check the support from the VPS with the following:
ls -lah /dev/fuse
If you are encountering issues please open a support ticket with our team.
