I have Fedora 21, which is a fedup from Fedora 20. My problem is that whenever I am using ps commaand, I am getting /usr/bin/dpkgd/ps: error while loading shared libraries: libprocps.so.1: cannot open shared object file: No such file or directory.This code was working perfectly when I had Fedora 20 installed. While doing Fedup, I got a bunch ofldconfig: /usr/lib/libOpenCL.so.1 is not a symbolic linkmessage, but the fedup went fine.Here are the output of the commands which might be relevant:$ which ps/bin/ps$ type psps is /bin/ps$ ldd /bin/psnot a dynamic executable$ ldd /usr/bin/dpkgd/ps    inux-gate.so.1 =>  (0xb77f7000)    libprocps.so.1 => not found    libsystemd-login.so.0 => /lib/libsystemd-login.so.0 (0xb77ae000)                                                                                                                                          libdl.so.2 => /lib/libdl.so.2 (0x467c7000)                                                                                                                                                                libc.so.6 => /lib/libc.so.6 (0x465f9000)                                                                                                                                                                  librt.so.1 => /lib/librt.so.1 (0x46a72000)                                                                                                                                                                libdw.so.1 => /lib/libdw.so.1 (0x47816000)                                                                                                                                                                libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x46854000)                                                                                                                                                          libpthread.so.0 => /lib/libpthread.so.0 (0x467ce000)                                                                                                                                                      /lib/ld-linux.so.2 (0x465ce000)                                                                                                                                                                           libelf.so.1 => /lib/libelf.so.1 (0x47695000)                                                                                                                                                              liblzma.so.5 => /lib/liblzma.so.5 (0x46edd000)                                                                                                                                                            libbz2.so.1 => /lib/libbz2.so.1 (0x46a7d000)                                                                                                                                                              libz.so.1 => /lib/libz.so.1 (0x467eb000)If I do a sudo yum reinstall procps, the problem goes away, even if the output of ldd does not change. But after restarting the computer, the problem returns. What could be the permanent solution of this problem?
