Elrepo Problem?

So much for elrepo being a painless way to get working Nvidia drivers…

Yum update (or just update glibc) says:

–> Processing Dependency: /usr/sbin/ldconfig for package:
–> Finished Dependency Resolution Error: Package: nvidia-x11-drv-304xx-304.123-1.el7.elrepo.x86_64 (@elrepo)
Requires: /usr/sbin/ldconfig
Removing: glibc-2.17-55.el7.x86_64 (@anaconda)
Not found
Updated By: glibc-2.17-55.el7_0.1.x86_64 (updates)
Not found You could try using –skip-broken to work around the problem

What do those ‘not found’s mean?

  • This isn’t elrepo’s fault.

    The glibc update changes the location of the ldconfig binary. It’s still in root’s path, but anything that had a hardcoded path as a requirement will break.

    The original glibc package provides both /usr/sbin/ldconfig and
    /sbin/ldconfig, while the updated package only provides /sbin/ldconfig.

    It means there’s no more /usr/sbin/ldconfig provided in the newer packages.

  • Ummm, great… I thought that was just the sort of breakage that
    ‘Enterprise’ OS versions were supposed to avoid. (I realize it’s not CentOS’s fault either).

    The whole ‘s’ concept was a bad idea to begin with. Why did they have to make it worse?

    Seems odd to say it twice. But what’s the right fix here?

  • Seems odd that with both the new and old glibc versions, rpm -q –whatprovides /usr/sbin/ldconfig says glibc-2.17-55.el7.x86_64
    or glibc-2.17-55.el7_0.1.x86_64
    yet yum doesn’t think so.

    I guess symlinks really are evil and only useful for job security…

  • RPM has been able to handle symlinks for a long time:

    $ rpm -ql kdelibs | grep libkunittest.so.4.13.3
    $ rpm -qf /lib64/libkunittest.so.4.13.3

    I presume that yum is querying RPM for information about installed packages, causing the installed version of glibc to “automagically”
    provide /usr/sbin/ldconfig. Let’s test:

    # ln -s /usr/sbin /foo
    # rpm -qf /foo/ldconfig
    # yum provides /foo/ldconfig

    glibc-2.17-55.el7_0.1.x86_64 : The GNU libc libraries
    Repo : @updates
    Matched from:
    Filename : /foo/ldconfig

    So yum has (and uses) more information about installed packages.
