Severity: important

Dear Maintainer,

I tried to install OpenGL libraries 25.1 series at experimental (i.e. 25.1.0-1)
in multiarch emvironment, some libraries / drivers built with llvm-20 conflict with another architectures.

For example, I make multiarch environment both amd64 and i386, to use
wine and steam mainly.

[...]

And, many libraries src:mesa depends mesa-libgallium, so,
packages built from src:mesa 25.1 aren't able to  install on multiarch environment (they are depended by Wine and Steam and more).

This issue is occured by changes of src:llvm-toolchain-20 1:20.1.4-1-exp1,

[ Sylvestre Ledru ]
    * Drop Multi-Arch: same from packages installing to non-multiarch paths.
    (Closes: #1102278)
    Thanks to Yuce Kurum for the patch

The patch dropped Multi-Arch: same from libllvmX. Is this a mistake?

IIUC, libllvmX has been installed to multilib path for years, and Bo
YU's original patch[1] didn't touch it.

Over and over again. This is a very serious problem, especially fo people using
Wine and/or Steam, so I think it needs to be fixed and process BUG as "Important"
or upper priority.

Regards,
Ohta.

Dear Maintainer,

I have the sane issue, I can't install mesa from experimental as I need amd64 and i386 but the packages conflict:

The following packages have unmet dependencies:
mesa-libgallium:i386 : Depends: libllvm20:i386 but it is not installable
mesa-vulkan-drivers:i386 : Depends: libllvm20:i386 but it is not installable E: Unable to correct problems, you have held broken packages.
E: The following information from --solver 3.0 may provide additional context:
Unable to satisfy dependencies. Reached two conflicting decisions:
1. libllvm20:i386=1:20.1.4-1~exp1 is not selected for install because:
1. mesa-opencl-icd:amd64=25.1.0-1 is selected as an upgrade
2. mesa-opencl-icd:amd64=25.1.0-1 Depends libllvm20
3. libllvm20:amd64 Conflicts libllvm20:i386
2. libllvm20:i386=1:20.1.4-1~exp1 is selected for install because:
1. mesa-libgallium:i386=25.1.0-1 is selected as an upgrade
2. mesa-libgallium:i386=25.1.0-1 Depends libllvm20:i386
3. libllvm20:i386 is available in version 1:20.1.4-1~exp1
