Back in Lucid multi-arch didn't exist in Ubuntu so firefox is definitely 64bit on a 64bit system as there's no way to install the 32bit version on Ubuntu through the distro packages. It's probably worth noting that the whole /lib32 and /lib64 is a convention used on Red Hat systems but not on Debian based systems. These directories may exist on an Ubuntu system but generally shouldn't be used to know if a software is 32bit or 64bit. The multi-arch way of doing that (since 11.04) is with /lib/<arch-triplet/<library> for any library being Multi-Arch:same: stgraber@castiana:~$ file /lib/i386-linux-gnu/libnih.so.1.0.0 /lib/i386-linux-gnu/libnih.so.1.0.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, BuildID[sha1]=0xa182c87dc0fde63db8ca47f9d30291ee3d5eb541, stripped https://wiki.ubuntu.com/MultiarchSpec - -- Stéphane Graber Ubuntu developer http://www.ubuntu.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCgAGBQJOvVLzAAoJEMY4l01keS1nwz8QALoCbgUTMQVtZwcBJHl4FJma iEJ1G2SWwti5NpCOaC8TSO1cUfoz1p36uHKaxywYlsIFb/+nsfXVi3Tq9vabzuP1 sbV/C6A1P3Io+C5f+8Smu6xNeRwY2N36KF1Ou8G6edOq9Hz4MbbdDzzle88faP5P 9hCt+tB8plTK4lzQPMIXLYsmhYQ//jCpId3x4uw4mgOQVoaC957HiVkiuG6qG+MO CtSmP9wclCLNxc5uEp1rxa6BDSjIunFazh7BUGUR7MsczkaBqJmGYgrN83FPqveB cFfgknuNQ8M0dqMlwZIDJGk502WubawcbFUBU1L6Z7MSo69YKFfdNnb6MZWK1OyC yibWkRsZHpdggMEvTGybHrX0rkY56YnbgJhV/I4GQKKEJi9RV9cB+AahmopuQFxq ZxGFdHMn0VuBQRr37iNsDETFSxDQmtgBEBB2hKcCt+Kg/zUzFH/aVKIyMIXjamf0 JGdi0zKrninWnGHeDXwmOus2JoLb/cfaI8aBmy58axN+iusa54HRy+Di5SNJiulV R4/SwkWHEAQMd6XXmouW1k8ThkpJtCsptofsKRbN6an6lIVbx8/95ipUH0huEHBF YieHGDWm2I8cBQMUV/DyOC3fmBNZKfxmzelpNFLf4Ra4mZHOpJd/TZ/ZJwyM2lJE T8GXQqrBHmTC/Hwdt/Dt =ngB8 -----END PGP SIGNATURE----- -- edubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/edubuntu-users
