missing all addons on addons store supervisor

Describe the issue you are experiencing

Hi! Long story short: All the addons from the official store disappeared without any clear explanation. I’ve installed 5.11 a couple of weeks ago and everything was running fine (i’ve managed to install 3 addons and some integration), but one day the official addons were missing. I’ve tried to upgrade to 5.12 but nothing has changed.

Some other info: I’ve installed the 5.12 on the same nuc a lot of times trying to understand if was some wrong configuration by my side (debian and ubuntu, using kvm and virtual box). At the end i moved to win10 and vmware, and tried the last for version of ha os. With the 5.12 the issue was always the same, but with 5.11-10-9 the add-ons were working.

What is the used version of the Supervisor?

supervisor-2021.03.6

What type of installation are you running?

Home Assistant Supervised

Which operating system are you running on?

Home Assistant Operating System

What is the version of your installed operating system?

What version of Home Assistant Core is installed?

It you have an eero router you need to disable ‘advanced security’ under discover —> eero secure

Nope. First of all, I already have eero secure advanced security disabled.

Secondly, I have a third instance of HomeAssistant (one that’s been slowly upgraded over the past year, as updates have come out) that is COMPLETELY UNAFFECTED by this issue. The repositories work great on that machine.

The two machines I’ve tried to setup since then, though, are totally broken with respect to the supervisor being able to manage addons. The only way to get any addon even installed is to take a snapshot from a working machine, and restore it to the newer machines.

To reiterate, this is NOT a problem with the eero. I have three instances of HA that I’m working with. The first, oldest one is a bit messy, but addons show up properly. Because it’s otherwise kind of chaotic, my thought was to start fresh with a new VM, but neither a HASSOS machine nor a Supervised Debian 10 64 bit installation are able to do anything with addons. They are all three on the same network.

I opened a bash instance in the hassio_supervisor docker container and I can ping google.com and facebook.com but I cannot ping github.com(I get the output “bad address”) which seems a bit selective. Looking into this a bit more it seems like this could be related to alpinelinux/docker-alpine#155 which could be the potential cause since it appears the supervisor uses alpine 3.13.
