Problem during installation process

I’m quiet new in HA. I’m tring to install HA 16.2 in a VirtualBox machine. After the process starts, in the web interface, I have the following error and the installation fails. 2025-10-20 21:56:57.172 WARNING (SyncWorker_1) [supervisor.host.sound] Can’t update PulseAudio data: Fail.
After this, in the web interface i find other errors like:2025-10-21 05:59:31.187 ERROR (MainThread) [supervisor.docker.interface] Can’t install ghcr.io/home-assistant/qemux86-64-homeassistant:2025.10.3: 500 Server Error for http+docker://localhost/v1.51/images/create?tag=2025.10.3&fromImage=ghcr.io%2Fhome-assistant%2Fqemux86-64-homeassistant&platform=linux%2Famd64: Internal Server Error ( dial tcp 140.82.121.34:443: connect: network is unreachable")
2025-10-21 05:59:31.188 WARNING (MainThread) [supervisor.homeassistant.core] Error on Home Assistant installation. Retrying in 30sec

I have tried a lot of times to start again, but evry time same problem.
