curl recently broken with v2?

[craff]

A dependency on curl seem to break the build:

Main error (missing package):

The following system packages will first need to be installed:
      libcurl4-gnutls-dev
  
  <><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>
  + /usr/bin/sudo "apt-get" "install" "-qq" "-yy" "libcurl4-gnutls-dev"
  - E: Failed to fetch http://azure.archive.ubuntu.com/ubuntu/pool/main/c/curl/libcurl4-gnutls-dev_7.81.0-1ubuntu1.6_amd64.deb  404  Not Found [IP: 40.119.46.219 80]
  - E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
  This command should get the requirements installed:
  
      apt-get install -qq -yy libcurl4-gnutls-dev

Consequence error:

This is a problem with package list not up to date. The following solves the issue:

      - run: sudo apt-get update
        if: ${{ matrix.os == 'ubuntu-latest' }}

Answer to the comment mentionned above:

I am not sure. depext is not supposed to do apt-get update for you. Only apt-get install.
I think the building of the container should include an apt-get install otherwise there is always a risk of
an ubuntu package not available, even if the base container is updated regularly, if you try to build at the wrong time
you get missing packages.
