dpkg -S was the very first thing I did but: ~$ dpkg -S /usr/lib/libc.so.6 dpkg: /usr/lib/libc.so.6 not found.
The link might have been created by some post-install script. Matt: which package list are you referring to? I don't have any of the extra packages you listed installed on my box so you must be referring to the list added in a comment by Lorenco Trichardt. Note that his error has to do with /usr/lib/libdl, while mine is related to /usr/lib/libc.so.6. I checked and I don't have a /usr/lib/libdl.so.2 on my system at all, so while his symptoms might be the same as my bug (this bug), the underlying cause is not the same. I don't know whether it's useful to open a second bug for the libdl problem or not. I don't know if the Juniper Network Connect is available for download generally, but I don't think this is the problem. The dates on the symlinks don't match up, and I ran ldd on the executables and all of them find /lib/libc, /lib/libm, /lib/libpthread, and /lib/libdl: libncui.so: linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/libdl.so.2 (0xb7ed8000) libz.so.1 => /usr/lib/libz.so.1 (0xb7ec4000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7eb0000) libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 (0xb7e68000) libm.so.6 => /lib/libm.so.6 (0xb7e43000) libc.so.6 => /lib/libc.so.6 (0xb7d23000) /lib/ld-linux.so.2 (0x80000000) ncdiag: linux-gate.so.1 => (0xffffe000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7ee6000) libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 (0xb7e9e000) libm.so.6 => /lib/libm.so.6 (0xb7e78000) libc.so.6 => /lib/libc.so.6 (0xb7d58000) /lib/ld-linux.so.2 (0xb7f0a000) ncsvc: linux-gate.so.1 => (0xffffe000) libdl.so.2 => /lib/libdl.so.2 (0xb7f0a000) libz.so.1 => /usr/lib/libz.so.1 (0xb7ef6000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7ee2000) libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 (0xb7e9a000) libm.so.6 => /lib/libm.so.6 (0xb7e75000) libc.so.6 => /lib/libc.so.6 (0xb7d55000) /lib/ld-linux.so.2 (0xb7f1f000) -- libc6 update for Edgy fails due to sanity check https://launchpad.net/bugs/81125 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
