No it seems that there is other path to reproduce the error. At least : if libc6 and libc6-i686 are correctly installed from unstable. Then I remove libc6-i686. I downgrade to libc6/testing. And I try again to upgrade. There is now a faillure. If I do: dpkg --ignore-depends=libc6 -i /var/cache/apt/archives/libc6-i686_2.6.1-3_i386.deb Then I can correclty configured libc6. when the upgrade of libc6 fails wahiba:~# ldd /usr/bin/perl linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/libdl.so.2 (0xb7fb1000) libm.so.6 => /lib/libm.so.6 (0xb7f8b000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7f73000) libc.so.6 => /lib/libc.so.6 (0xb7e2b000) libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7dfd000) /lib/ld-linux.so.2 (0xb7fd1000) after the manual forced installation of libc6-i686: wahiba:~# ldd /usr/bin/perl linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7f5c000) libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb7f37000) libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xb7f20000) libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7dd8000) libcrypt.so.1 => /lib/i686/cmov/libcrypt.so.1 (0xb7daa000) /lib/ld-linux.so.2 (0xb7f7d000) Hope this help -- Gallien Matthieu
