[ghost]

• VSCode Version: 1.72.0, 1.72.2
• Local OS Version: Windows 10
• Remote OS Version: (Ubuntu 20.04)
• Remote Extension/Connection Type: Containers (0.262.0) or SSH + Containers (0.262.0)

Steps to Reproduce:

1. (Open a folder on SSH)
2. Add Dev Container Configuration Files

A corporate proxy may be involved.

I ran into same issue too. And my environment is behind a corporate proxy as well.
As a workaround, I downgraded "Dev Containers" extension from v0.262.3 to v0.255.4.

I'm having the exact same problem, rolling back fixed the issue for me.
I'm not behind any proxy.

seems fixed...apparently it was a remote http 503 server issue.

Downgrading to 0.255.4 resolved the templates apply issue for me

I'm behind a company proxy using self-signed SSL certificates and facing a similar issue like this one. I can see the following in my "Dev Container Logs" when using "Dev Containers" plugin version 0.266.1 and trying to add a Dev Container Configuration:

[8682 ms] Failed to get registry auth token with error: Error: unable to get local issuer certificate
[8798 ms] Failed to fetch template manifest for ghcr.io/devcontainers/templates/alpine:latest
[8799 ms] Failed to fetch template 'ghcr.io/devcontainers/templates/alpine:latest'.

Downgrading the plugin to 0.255.4 also fixes the error for me.

Downgrading to 0.255.4 did not work for me
