Is it regression?

Yes

Expected behavior

Darcs package should be available and installable as per regular Ubuntu 24.04 LTS

Repro steps

Using this configuration should demonstrate the failure:

name: Build
on:
  push:
    branches:
      - master
  pull_request:
jobs:
  build:
    strategy:
      fail-fast: false
      matrix:
        os:
          - ubuntu-24.04
          - ubuntu-22.04

    runs-on: ${{ matrix.os }}

    steps:
      - name: Update Ubuntu
        if: runner.os == 'linux'
        run: |
          sudo apt-get update
          sudo apt-cache search darcs
          sudo apt-get install darcs

Ubuntu 24.04 will fail because it can't install darcs while 22.04 will pass.

Hi @tmcgilchrist Can you please try the following workflow, It should allow you to install Darcs on Ubuntu 24 as well.

name: Build
on: [push, pull_request]

jobs:
  build:
    strategy:
      fail-fast: false
      matrix:
        os:
          - ubuntu-24.04
          - ubuntu-22.04

    runs-on: ${{ matrix.os }}

    steps:
      - name: Update Ubuntu
        if: runner.os == 'linux'
        run: |
          sudo apt-get update
          sudo apt-get install -y curl
          curl -sSL https://get-ghcup.haskell.org | sh -s -- -y
          source $HOME/.ghcup/env
          ghcup install ghc 8.10.7
          ghcup set ghc 8.10.7
          ghcup install cabal 3.4.0.0
          ghcup set cabal 3.4.0.0
          cabal update
          cabal install darcs

This breaks the ocaml-setup action, which depends on darcs. I don't think the @RaviAkshintala's workaround will get ocaml-setup working since that action actually executes apt-get install darcs.

[tmcgilchrist]

@nlsandler that's correct, we would need changes in setup-ocaml. I'd be ok if this package wasn't installable on Ubuntu 24.04 on my desktop docker but it is which is why I'd reported it here.

There is an upstream bug report for Debian on this package https://tracker.debian.org/pkg/darcs with the specific failure here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1054953 I don't know whether this impacts downstream Ubuntu or the images available in runner-images???

[psafont]

Is there any update on this issue? I'm also hitting this issue when running setup-ocaml on ubuntu-latest

Hi @tmcgilchrist Hopefully your issue is resolved here, We are closing this issue. Thanks!
