Unable to update hassio to 0.69

Installation Home Assistant OS

UI informs me a new update is available, but trying to upgrade nothing happens. Hassio system logs show the following

18-05-12 18:30:23 INFO (SyncWorker_2) [hassio.docker.interface] Update docker 0.68.1 with homeassistant/qemux86-64-homeassistant:0.69.0

I am running hassio on a ESXi VM. hassio works fine and I can access hassio from outside my network so port forwarding works fine. However, I am unable to update hassio, nor am I able to update addons (all with the 404 error).

How can I troubleshoot this?
Is this a networking problem in my environment?
Is the build not tagged correctly?
Help is appreciated!!

Issue was not enough space on the harddisk of the VM. I resized the disk in ESXi and then using gparted (linux boot) and now it is solved. Thanks to user cogneato helping with the roubleshooting!
