Official add-ons can't be installed, but community add-ons are fine

1

Hello,

I just installed HomeAssistant 11.1 in a VM on my Synology NAS. When trying to install the Samba add-on, I got the following error:

Can't install official Add-ons
Can't install official Add-ons1080×358 27.2 KB

Installing any community add-on on the other hand works just fine (I installed Home Panel and Node Red).
What am I missing here?
