Hey Guilhem. Is it possible that your fix doesn't work on not-yet-usr-merged systems?
I get here: $ env --unset=LD_PRELOAD ldd /sbin/cryptsetup | sed -nr '/.*=>\s*(\S+)\/libargon2\.so\..*/ {s//\1/p;q}' /usr/lib/x86_64-linux-gnu but: $ dpkg -L libgcc-s1 /lib/x86_64-linux-gnu /lib/x86_64-linux-gnu/libgcc_s.so.1 On non-usr-merged systems, copy_libgcc doesn't seem to include it then. Please don't solve this by depending on usr-merge (not that I'd have anything against it, but I'd like to migrate my systems only when this becomes the next stable). Cheers, Chris.
