I’m trying to update my Hassio on docker to 0.86 and getting the 404 error for image not found.
404 Client Error: Not Found (“manifest for homeassistant/qemux86-64-homeassistant:0.86.0 not found”).
Same here.
Doesn’t look like that component has been updated yet. It’s still listed on docker hub at 0.85.1

Weird that it had to show upgrade available when there is none for my image . Hopefully devs fix it soon . 
can’t wait to update
Could also be an Insufficient space issue.
See here for how to confirm: Cant upgrade to 86.0
I ran into this issue when trying to upgrade to 0.85.0 
No.
The image isn’t built.

Just need to wait.
It always surprises me when a new version is announced, and Blog post made about it, and none of the images are ready to download. 
Just wait 2-3hrs until when all the images are updated with the new version tag, then post the blog and homepage update to avoid all of these “I can’t update” posts.
