How to create missing debs for focal 32 bit?

This description was done using version v0.6 of "lxc-ubuntu-32bit".

According to my experiences from the past, we need this deb:

  • netplan.io

Within this pagagraph, I describe how to build it.

$ cd .../lxc-ubuntu-32bit-v0.6
$ ./create-32bit-image.sh -k focal focal-build
...

  # There is a folder named "focal-build" afterwards

Configure Build Chroot

$ cat focal-build/etc/apt/sources.list|sed -e "s/^deb /deb-src /"|sudo tee focal-build/etc/apt/sources.list.d/deb-src.list >/dev/null
$ sudo mkdir focal-build/src

Running A Test Build

$ PACKAGE=(package-name)
$ ./build.sh focal-build "${PACKAGE}"

Typically, these are the outcomes:

  • The build succeeds without any issue
  • The build preparation fails because of missing dependencies -> build the dependencies
  • The build fails (not observed so far)

Running Test Build Of netplan.io

$ PACKAGE=netplan.io
$ ./build.sh focal-build "${PACKAGE}"
...
The following packages have unmet dependencies:
 builddeps:netplan.io : Depends: python3-coverage but it is not installable
                        Depends: python3-netifaces but it is not installable
                        Depends: pandoc but it is not installable
                        Depends: openvswitch-switch but it is not installable
E: Unable to correct problems, you have held broken packages.

So there are missing dependencies. We have to build these and come back to "netplan.io" once all of them are ready!

Tree Of Missing Debs

Here is the consolidated list of missing debs:

  • netplan.io
    • python3-coverage
    • python3-netifaces
    • pandoc
      • ghc
        • ghc
    • openvswitch-switch
      • libdpdk-dev
        • libfdt-dev
  • isc-dhcp-client (optional)
    • libbind-export-dev (optional)
  • logrotate (optional)

Special Case pandoc

Tryining to build pandoc leads to the dependency "ghc" (somehow related to Haskall) which has a dependency to itself. Currently, I have no idea on how to continue here, so I'm going to modify all packages depending on pandoc. I'll remove pandoc from these.
