Bug#1064191: openjdk-8: fails to install on i386 mantic, focal and jammy

[Vladimir Petko]

Package: openjdk-8
Severity: wishlist
Tags: patch
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu noble ubuntu-patch

Dear Maintainer,

  openjdk-8 402-ga-2 introduced changes that make the package fail to install
in i386 Ubuntu noble.
  binfmt-support might not be installed and /usr/share/binfmts directory might
not exist. This causes postinstall script to fail in a new installation.
  ATK wrapper package for i386 is not present in stable releases of Ubuntu and
will require SRU process to be introduced. This makes package uninstallable.

 Would it be possible to consider the following changes:

  * Fix installation issue on i386 (LP: #2053110):
    - d/rules: build without atk bridge on i386 for Ubuntu versions that
      do not have it.
    - d/JB-jre-headless.postinst.in: check that /usr/share/binfmts exists
      before trying to delete it.


Thanks for considering the patch.
