Hi.

(skiping 10000 lines of apt errors...)

0102 03:27:47.118899 E: Unable to satisfy dependencies. Reached two conflicting decisions:
0102 03:27:47.118905    1. mesa-libgallium:i386 is selected for install because:
0102 03:27:47.118911       1. mesa-utils-bin:i386=9.0.0-2+b2 is selected for install
0102 03:27:47.118918       2. mesa-utils-bin:i386 Depends libegl1:i386
0102 03:27:47.118924       3. libegl1:i386 Depends libegl-mesa0:i386
0102 03:27:47.118934       4. libegl-mesa0:i386 Depends mesa-libgallium:i386 (= 25.3.2-2)
0102 03:27:47.118943    2. mesa-libgallium:i386 Depends libllvm21:i386 (&gt;= 1:21.1.0)
0102 03:27:47.118950       but none of the choices are installable:
0102 03:27:47.118960       - libllvm21:i386 is not selected for install because:
0102 03:27:47.118969         1. mesa-opencl-icd:amd64=25.3.2-2 is selected for install
0102 03:27:47.118980         2. mesa-opencl-icd:amd64 Depends libllvm21 (&gt;= 1:21.1.0)
0102 03:27:47.118990         3. libllvm21:amd64 is available in version 1:21.1.8-1
0102 03:27:47.118999         4. libllvm21:i386 Breaks libllvm21 (!= 1:21.1.8-1+b1)

I understand libllvm21 in testing is not in sync between amd64 and i386
for last few days, and probably will be in sync in few days

libllvm21
  forky (testing) (libs): Modular compiler and toolchain technologies, runtime library
     1:21.1.8-1+b1: armhf i386
     1:21.1.8-1: amd64 arm64 ppc64el riscv64 s390x

But, that begs the question. Why I cannot coinstall different version
for libllvm21:amd64 and different for libllvm21:i386 ?

Regards,
Witold
