Steps to Reproduce:

1. Browse https://github.com/microsoft/vscode-remote-try-java
2. Click "Dev Containers: Open" banner

Does this issue occur when you try this locally?: Yes Does this issue occur when you try this locally and all extensions are disabled?: Yes

[tk0miya]

The error will be resolved and the dev container will invoked well if I modify the bootstrap.Dockerfile to run apk add before modifying TLS certs.

I'm not sure where this certs file came from and why it's needed. But it seems broken on my environment.

[chrmarti]

We read the OS certificates with /usr/bin/security find-certificate -a -p on macOS and add these to the container to support corporate environments with custom certificates. Not sure why these certificates break access to dl-cdn.alpinelinux.org for you.

[tk0miya]

Thank you for the hint.

As a trial, I removed one of the certificate entries from /etc/ssl/certs/ca-certificates.crt. Then "apk add" works fine. The certificate I removed is issued by Apple (CN=com.apple.kerberos.kdc).

[chrmarti]

That shouldn't affect verification of the certificate for dl-cdn.alpinelinux.org. What are the certificates in ca-certificates.crt right before and right after this certificate? Does removing some other certificate instead of this also make it work or did you try one after the other to find this one? What is the size of ca-certificates.crt?

[tk0miya]

What are the certificates in ca-certificates.crt right before and right after this certificate?

This is the last entry of my ca-certificates.crt. The before entry is CN=com.apple.systemdefault.

Does removing some other certificate instead of this also make it work or did you try one after the other to find this one?

Surprisingly, it also works fine if I remove another one instead (ex. second from last, 3rd from last, ...)

What is the size of ca-certificates.crt?

[chrmarti]

Does running update-ca-certificates show any relevant output? Does it also make it work (without removing any certificate)?

[tk0miya]

Does running update-ca-certificates show any relevant output?

I got a warning. But I'm not sure this is related or not.

root ➜ / $ update-ca-certificates
WARNING: Skipping duplicate certificate in file ca-cert-ISRG_Root_X1.pem

Does it also make it work (without removing any certificate)?

Unfortunately, no. The TLS error still happens.

BTW, there are 5 certificates copied from the host to /usr/local/share/ca-certificates on my PC. Two are for root CA, one was installed for tech conf (unused now), and two are for Apple/macOS.

        Issuer: CN = com.apple.kerberos.kdc, O = System Identity
        Subject: CN = com.apple.kerberos.kdc, O = System Identity

In my case, removing the unused cert resolves the error. But I feel the true problem is not resolved yet. Is it still needed to investigate my error for other people?
