Description
Hi guys,

Recently when trying create an image off of the ubuntu 22.04 template from the main branch I see that during the provisioning of the install git step. It always fails here

Note the log file is quite long so i trimmed it to just a few lines from where the error has occurred:

azure-arm.build_image: For release candidates, go to https://launchpad.net/~git-core/+archive/candidate . azure-arm.build_image: More info: https://launchpad.net/~git-core/+archive/ubuntu/ppa azure-arm.build_image: Removing repository. azure-arm.build_image: Disabling deb entry in /etc/apt/sources.list.d/git-core-ubuntu-ppa-jammy.list azure-arm.build_image: Removing disabled deb entry from /etc/apt/sources.list.d/git-core-ubuntu-ppa-jammy.list azure-arm.build_image: Removing disabled deb-src entry from /etc/apt/sources.list.d/git-core-ubuntu-ppa-jammy.list ==> azure-arm.build_image: Provisioning step had errors: Running the cleanup provisioner, if present...

Looks like it's specific to this particular step as part of the git installation

Removing disabled deb-src entry from /etc/apt/sources.list.d/git-core-ubuntu-ppa-jammy.list

Repro steps

Have an azure pipeline running that checkouts this repository and use packer to build the ubuntu22.04 image referencing this repository's ubuntu22.04 template.

Hi @iZnoGod722 , Thank you for bringing this issue to our attention.
We are not facing issue while building Ubuntu-22 images, our builds appear green, could please try to build the same.
if error ,revert with error logs. regards

Closing this as I found out what the issue is.

It is actaully failing to perform the following:

ssh-keyscan -t rsa,ecdsa,ed25519 github.com >> /etc/ssh/ssh_known_hosts
ssh-keyscan -t rsa ssh.dev.azure.com >> /etc/ssh/ssh_known_hosts

The temp VM spun up by Packer is using a private VNET. I found out that our company's firewall is blocking port 22.
