Update home assistant operating system from virsh guest console
Update to Home Assistant Operating System is based on its release in Github. It means we may fall in the Error updating Home Assistant Operating System: Can't fetch OTA update from https://github.com/home-assistant/operating-system/releases/download/13.1/haos_ova-13.1.raucb in the place where GitHub is not accessible.
So we can make it by modifying the release_url.
Proxying Github
Check my another post 如何解决github访问慢的问题（中文）.
For example, add proxy link https://gh.api.99988866.xyz/ ahead of the original release link.
Deep track it
Check the error log again.
2024-08-24 21:33:44.051 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [139950367721920] Error updating Home Assistant Operating System: Can’t fetch OTA update from https://github.com/home-assistant/operating-system/releases/download/13.1/haos_ova-13.1.raucb: Traceback (most recent call last): File “/usr/src/homeassistant/homeassistant/components/hassio/update.py”, line 213, in async_install await async_update_os(self.hass, version) …
This script file /usr/src/homeassistant/homeassistant/components/hassio/update.py will be the key.
Let’s have a look in its source. It’s easy to find out the following code snippet.
class SupervisorOSUpdateEntity(HassioOSEntity, UpdateEntity):
"""Update entity to handle updates for the Home Assistant Operating System."""
...
@property
def release_url(self) -> str | None:
"""URL to the full release notes of the latest version available."""
version = AwesomeVersion(self.latest_version)
if version.dev or version.strategy == AwesomeVersionStrategy.UNKNOWN:
return "https://github.com/home-assistant/operating-system/commits/dev"
return (
f"https://github.com/home-assistant/operating-system/releases/tag/{version}"
)
async def async_install(
self, version: str | None, backup: bool, **kwargs: Any
) -> None:
"""Install an update."""
try:
await async_update_os(self.hass, version)
except HassioAPIError as err:
raise HomeAssistantError(
f"Error updating Home Assistant Operating System: {err}"
) from err
There is a release_url function to generate the part of the link for the release. Then we have to modifying it to
@property
def release_url(self) -> str | None:
"""URL to the full release notes of the latest version available."""
version = AwesomeVersion(self.latest_version)
if version.dev or version.strategy == AwesomeVersionStrategy.UNKNOWN:
return "https://gh.api.99988866.xyz/https://github.com/home-assistant/operating-system/commits/dev"
return (
f"https://gh.api.99988866.xyz/https://github.com/home-assistant/operating-system/releases/tag/{version}"
)
Config it from virsh guest console
Open a guest console via virsh.
virsh console hass
root
Check docker root directory.
docker info
We can see the Docker Root Dir item. Mostly, it should be /mnt/data/docker.
Find the script file /usr/src/homeassistant/homeassistant/components/hassio/update.py with:
cd /
find . -path \*/usr/src/homeassistant/homeassistant/components/hassio/update.py
It will list all full path for this file. For example,
./mnt/data/docker/overlay2/356af2cef9b08a2162030badae8304fa4f2ae7f6544efb1a78b88e45472f7c90/diff/usr/src/homeassistant/homeassistant/components/hassio/update.py
./mnt/data/docker/overlay2/cc97cec3597fd6ed024f0f1af2a7e06e60df7a27ec03304342198257c7bb688d/diff/usr/src/homeassistant/homeassistant/components/hassio/update.py
./mnt/data/docker/overlay2/f8c72160e7488a7c152815e67a7f220f052e7b50d7fc606ee778099c2256237a/merged/usr/src/homeassistant/homeassistant/components/hassio/update.py
./var/lib/docker/overlay2/356af2cef9b08a2162030badae8304fa4f2ae7f6544efb1a78b88e45472f7c90/diff/usr/src/homeassistant/homeassistant/components/hassio/update.py
./var/lib/docker/overlay2/cc97cec3597fd6ed024f0f1af2a7e06e60df7a27ec03304342198257c7bb688d/diff/usr/src/homeassistant/homeassistant/components/hassio/update.py
./var/lib/docker/overlay2/f8c72160e7488a7c152815e67a7f220f052e7b50d7fc606ee778099c2256237a/merged/usr/src/homeassistant/homeassistant/components/hassio/update.py
I cannot recognize which is the right one. Then I modified the first three files (they are all under the Docker root directory).
vi /mnt/data/docker/overlay2/356af2cef9b08a2162030badae8304fa4f2ae7f6544efb1a78b88e45472f7c90/diff/usr/src/homeassistant/homeassistant/components/hassio/update.py
Retry to update
Go back to homeassistant lovelace and you can see the update task under the Settings.
It works this time for me. And best wishes to you.
