Error updating Home Assistant Operating System: Cannot connect to host github.com:443

[p-mitana]

Describe the issue you are experiencing

In short – Home Assistant lists an available update, but I cannot install it – it says it cannot connect to GitHub. Running ha os update command also fails. Copying the link and downloading the file via wget works fine though, the file starts being downloaded:

There already has been an issue for that – #3525 – but it has been closed and said to apparently be a network error. Also there were suspicions that it could be related but some GitHub problems. However:

• I don't expect it to be a network problem, as I can fetch the exact same file from the same terminal session that I cannot update via from which the ha os update command fails
• I don't also expect it to be related with any GitHub failure, as a couple of weeks have passed and the problem persists
• Also, after 12.4 -> 13.0 update failed, the 13.1 came out and I still cannot update from 12.4.
• Also, I have seen other reports from other users in the forum having the same problem – for example in this topic.

What operating system image do you use?

ova (for Virtual Machines)

What version of Home Assistant Operating System is installed?

12.4

Did the problem occur after upgrading the Operating System?

No

Hardware details

USB devices – 2x SkyConnect. HAOS is installed in a VM. Host is Ubuntu 24.04 on a NUC type x86-64 computer. Hypervisor is KVM I expect.

Steps to reproduce the issue

1. Enter terminal
2. Run ha os update
3. Alternatively, just try to update OS via GUI

Anything in the Supervisor logs that might be useful for us?

There's indeed something fishy... I have replied on the community forums, let's follow up there.

This comment might help.

Actually my issue was solved by replacing a quite old router that I had. Still, I expect the issue is be relevant for some users and specific configurations.
