Urgent : SSH Timeout with VirtualBox and ubuntu iso

[rohank63]

Hi Team, I am having ssh timeout issues for the last 2 days. I read out different articles (stackoverflow / packer doc) and tried different ways but the issue still persists. I would be thankful if anyone can solve it.

I am getting this repeatedly, this goes on for more than couple of hours. And after the timeout specified in my config I get timeout.

 Attempting SSH connection to 127.0.0.1:4222...
 [DEBUG] reconnecting to TCP connection for SSH
 [DEBUG] handshaking with SSH
 [DEBUG] SSH handshake err: SSH handshake err: ssh: handshake failed: read tcp 127.0.0.1:49743->127.0.0.1:4222: read: connection reset by peer

I am using VitualBox 7.1.4 , and Packer v1.11.2 on Mac M3 .

In Virtual Box I can see network as NAT with port forwarding enabled.

Hello,

Since the latest version of macos (15.1), our VM deployment on Proxmox has stopped working, and we have SSH related errors.

We have tested the deployment on Linux systems where it works as intended, but we're encountering SSH errors on multiple Mac M3 running the latest macOS version.

We need to investigate what's happening, but I suspect the latest macOS update is breaking or interfering with Packer...

Hello,

I have the same problem on macOS 15.1 on M3.

From Linux, I don't have any issue.

@KinoFool @Xavier2p
But I am using Sonoma 14.7

[Xavier2p]

Sonoma 14.7 is the last version too. I think it's a security bug or something like that @rohank63

Same here on Mac os 15.x

Should be fixed by #13214.

[lbajolet-hashicorp]

As mentioned in the related PR by @edigaryev (thanks again!), this will be fixed with the next Packer release, i.e. 1.12.0, scheduled for next January.

In the meantime, if you hit this bug, you can play with the nightly, available on Github: https://github.com/hashicorp/packer/releases/tag/nightly

Note: there'll be a bit of latency until it's available, so if you have an error with today's nightly, you can try again when it's re-built tomorrow.
