[Bug 2100775] Re: python3-minimal wants to install twice when installing amd64 and arm64 packages

[Stefano Rivera]

The issue may be in your apt sources, or in packages you already have
installed in that docker base system.

In a minimal environment, with these sources:

deb [arch=amd64,i386] http://archive.ubuntu.com/ubuntu noble main universe
deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports noble main universe
deb [arch=amd64,i386] http://archive.ubuntu.com/ubuntu noble-updates main universe
deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports noble-updates main universe
deb [arch=amd64,i386] http://archive.ubuntu.com/ubuntu noble-security main universe
deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports noble-security main universe

I get success:

# apt install -y libasound2-dev:amd64 libasound2-dev:arm64 libasound2-dev:i386 libpipewire-0.3-dev:amd64 libpipewire-0.3-dev:arm64 libpulse-dev:amd64 libpulse-dev:arm64 libudev-dev:amd64 libudev-dev:arm64

Title:
  python3-minimal wants to install twice when installing amd64 and arm64
  packages

Status in python3-defaults package in Ubuntu:
  Incomplete

Bug description:
  When adding the ports repository to cross compile from amd64 to arm64,
  some arm64 dependencies tries to install python3-minimal:arm64 which
  conflicts with the already installed python3-minimal:amd64.

  I suspect this is a packaging mistake as 22.04 didn't have this issue
  and I've noticed this in 24.04.

  I believe some packages should have a virtual dependency on
  python3-minimal without specifying which architecture it uses right?
