libltdl-dev isn't present on Ubuntu 24.04, but was present on 22.04

[KKhanhH]

Description

libltdl-dev is a package recommended by libtool. However, while libtool is installed on both images, libltdl-dev is only present on 22.04. This might break workflows as a result of the migration of ubuntu-latest to 24.04 without an obvious reason.

Hi @KKhanhH , Thank you for bringing this issue to our attention. We are looking into this issue and will update you on this issue after investigating.

Hi @KKhanhH Can you please add the following workaround to your workflow file for Ubuntu 24, It is currently passing.

     - name: Install libltdldev
      run: sudo apt-get update && sudo apt-get install -y libltdl-dev

FYI, refer https://github.com/RaviAkshintala/libxcrypt-build-test/actions/runs/12664428397/workflow#L28 , Thanks.

Hi @RaviAkshintala, yes it does pass if explicitly installed. I'm requesting that it be included in the default image since it was included in 22.04 by default without an explicit installation step.

I believe some stuff was removed from the template file (I'm seeing a similar issue with missing ODBC-related stuff). e.g. this script:

https://github.com/actions/runner-images/blob/main/images/ubuntu/scripts/build/install-mssql-tools.sh

is not present in https://github.com/actions/runner-images/blob/main/images/ubuntu/templates/ubuntu-24.04.pkr.hcl whereas it was present in 22:

https://github.com/actions/runner-images/blob/main/images/ubuntu/templates/ubuntu-22.04.pkr.hcl#L312

Here's a diff snippet of the removals 22 -> 24:

-      "${path.root}/../scripts/build/install-aliyun-cli.sh",
-      "${path.root}/../scripts/build/install-heroku.sh",
-      "${path.root}/../scripts/build/install-oc-cli.sh",
-      "${path.root}/../scripts/build/install-leiningen.sh",
-      "${path.root}/../scripts/build/install-mono.sh",
-      "${path.root}/../scripts/build/install-mssql-tools.sh",
-      "${path.root}/../scripts/build/install-sqlpackage.sh",
-      "${path.root}/../scripts/build/install-oras-cli.sh",
-      "${path.root}/../scripts/build/install-rlang.sh",
-      "${path.root}/../scripts/build/install-sbt.sh",
-      "${path.root}/../scripts/build/install-terraform.sh",

If these removals were intentional, they should be marked as a "breaking change" in some fashion.
