    Recuring Crashes libz.so.1.2.8

    I am running 13.04 and have repeat crashes every 2 - 3 days. An error message, see attachment, quite often appears. Can I delete the file /libz.so.1.2.8 or will this wreck a package? Alternatively, can this file be replaced by another file?

    zlib1g is part of a default install, without which you wouldn't have much of an install, so it's likely still installed, (.2.7.dfsg-13ubuntu2 in raring, libz.so.1.2.7
    ck. with
    Code:
    apt-cache policy zlib1g
    However you've also caused libz.so.1.2.8 to be installed to /usr/local/lib, why did you do that?

    Hi, I don't know how I managed to load the file at /usr/local/lib. However it was done, it was by accident. Does this mean I can remove it from this location?

    If you go about it properly, yes.

    Did you ck. with apt-cache that the raring zlib1g package is installed & only that package?
    What's in /usr/local/lib concerning libz ?
    Code:
    ls /usr/local/lib |grep libz
    As far as your posted error message - it's saying a program that uses libz in /usr/local/lib crashed, what program was that?

    Just to see something - assuming default repo nautilus is used - what's this show?
    Code:
    ldd /usr/bin/nautilus |grep libz.so
    *if you decide to just go ahead & remove that file(s) in /usr/local/lib then you better run this after removing but before logging out or restarting
    (assuming repo zlib1g is installed
    Code:
    sudo ldconfig

    Hi MC4MAN thanks for the help.

    The terminal outputs you asked about are:

    colin@colin-MS-7309:~$ apt-cache policy zlib1g
    zlib1g:
    Installed: 1:1.2.7.dfsg-13ubuntu2
    Candidate: 1:1.2.7.dfsg-13ubuntu2
    Version table:
    *** 1:1.2.7.dfsg-13ubuntu2 0
    500 http://gb.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
    100 /var/lib/dpkg/status
    colin@colin-MS-7309:~$ ls /usr/local/lib |grep libz
    libz.a
    libz.so
    libz.so.1
    libz.so.1.2.8
    colin@colin-MS-7309:~$ ldd /usr/bin/nautilus |grep libz.so
    libz.so.1 => /usr/local/lib/libz.so.1 (0x00007fea76ed9000)
    colin@colin-MS-7309:~$

    I am afraid these don't mean much to me? I am grateful for any help.

    Sure looks like you built & installed zlib.
    (if you still have source folder you could cd to it in a terminal & run sudo make uninstall or just do manually as in -

    Open a terminal & run this command
    Code:
    sudo rm -f /usr/local/lib/libz.*
    Then maybe not needed but run anyway
    Code:
    sudo ldconfig
    Now ck. that nautilus is using the proper libz -
    Code:
    ldd /usr/bin/nautilus |grep libz.so
    (should > to /lib/x86_64-linux-gnu/libz.so.1 or the blue would be 'i386-linux-gnu' if on a 32 bit install

    If all is well there are likely a few other files in /usr/local/ that can be removed, ck. & remove
    (look for
    /usr/local/lib/pkgconfig/zlib.pc
    /usr/local/share/man/man3/zlib.3 #may be 3 or may be different number
    /usr/local/include/zconf.h
    /usr/local/include/zlib.h
