SteamOS can’t install Steam (because SteamOS broke the Debian multiarch mechanism)

[illwieckz]

Hi, installing libssl1.0.0 for both i386 and amd64 architecture from SteamOS repository does not work at all.

The head of the /usr/share/doc/libssl1.0.0/changelog.Debian.gz. file inside the libssl1.0.0:i386=1.0.1e-2+deb7u4+bsos1 package contains:

openssl (1.0.1e-2+deb7u4+bsos1) stable; urgency=low

  * Building openssl for project steamos:alchemist:main repository main
    arch i586 srcmd5 eb7fc8740831114e8be4e52be971d5f9

Because this file is unique regardless of the architecture, it becomes impossible to install multiple architecture versions of the same package

It works with Debian packages, not with yours. Something in your building tools breaks the multiarch system.

Please do not write arch-centric changelog neither common files inside multiarch Debian package

Hi,

Since you deleted the 1.0.1e-2+deb7u4 version from your repository, SteamOS can’t be installed successfully on a x86_64 system if you want to install 32 bit binaries (like Steam).

Nobody can install libssl for both 32bit and 64 bit binaries on SteamOS, because your packages are broken, and your package are broken because the changelog.Debian.gz are different on the two packages for the same version.

This file has the same path in the two packages because this file is arch-independent. But the package itself is arch-centric, so it is not allowed to have different changelog files for two packages of the same binary for two differents architectures.

You broke the Debian multiarch system.

SteamOS is unusable.

[illwieckz]

steam official package depend on curl which depend on libculr3 which depend on libssl1.0.0, so SteamOS can’t install Steam.

[illwieckz]

I’ve renamed this issue from:

Cannot install both libssl1.0.0:i386 and libssl1.0.0:amd64 on SteamOS from Steam repository (please do not write arch-centric changelog inside multiarch Debian package)

to:

SteamOS can’t install Steam (because SteamOS broke the Debian multiarch mechanism)

Fixed in today's alchemist_beta release http://steamcommunity.com/groups/steamuniverse/discussions/1/540743756995697451/

Thanks, it works.
