When will this work normally again?

Hello @LinuxSuRen - Thanks for raising this PR.
However, we have decided to keep oras out of Ubuntu-24.04` image as it was not much in use.
However, let's keep this PR open for few weeks to gauge the same.
Thanks.

hi @subir0071 thanks for your response. But do we have any data shows oras is not much in use?

Hi @TegarXLu @subir0071, same question with @LinuxSuRen . Removing oras out of Ubuntu-24.04 image looks breaking to existing oras users. Could you please help clarify it? Do you have any usage data as justification?

[subir0071]

Apart from our internal monitors, public forums like this are also very important to gauge the popularity and demand of tools and packages.
Unfortunately, we are still unable to include oras to the runner image, which we intend to keep slim.
Please include oras installation step into your workflow to continue using it.

Here is a sample workflow for the same. It takes around 1sec to get it installed which reduces the need to pre-package it in the image as the installation is almost effortless in terms of time and complexity -
