Package: libunwind-14t64
Version: 1:14.0.6-20
Severity: serious
Justification: unpack error

Hi,

attempting to coinstall libunwind-14t64 fails for e.g. amd64 and
ppc64el:

| Preparing to unpack .../libunwind-14t64_1%3a14.0.6-20_ppc64el.deb ...
| Unpacking libunwind-14t64:ppc64el (1:14.0.6-20) ...
| dpkg: error processing archive /var/cache/apt/archives/libunwind-14t64_1%3a14.0.6-20_ppc64el.deb (--unpack):
|  trying to overwrite shared '/usr/lib/llvm-14/lib/libunwind.so.1.0', which is different from other instances of package libunwind-14t64:ppc64el
| Errors were encountered while processing:
|  /var/cache/apt/archives/libunwind-14t64_1%3a14.0.6-20_ppc64el.deb
| E: Sub-process /usr/bin/dpkg returned an error code (1)

Please drop Multi-Arch: same from the package.
