When I run "yum update" on my FC-4 system (upgraded from FC-3) I get a large number of dependency errors of which the following are a sample: ================================================ ... --> Processing Dependency: libcrypto.so.5 for package: mysql-server --> Processing Dependency: libcrypto.so.5 for package: kdenetwork --> Processing Dependency: libssl.so.5 for package: samba --> Processing Dependency: libssl.so.5 for package: kdesdk --> Finished Dependency Resolution Error: Missing Dependency: libssl.so.5 is needed by package postgresql-libs Error: Missing Dependency: libcrypto.so.5 is needed by package authd ... ================================================ What is puzzling (to me) is that I have libssl.so.5 and libcrypto.so.5 , eg ================================================ [root@alfred tim]# locate libssl.so.5 /lib/libssl.so.5 [root@alfred tim]# ls -ls /lib/libssl.so.5 4 lrwxrwxrwx 1 root root 16 Jun 14 20:10 /lib/libssl.so.5 -> libssl.so.0.9.7f [root@alfred tim]# rpm -qf /lib/libssl.so.5 file /lib/libssl.so.5 is not owned by any package ================================================ As far as I can see, files installed by a package as symbolic links are not regarded as belonging to the package? I suspect my problem may be that yum installed these files as part of the i686 version of openssl : ================================================ [root@alfred tim]# grep openssl /var/log/rpmpkgs openssl-0.9.7f-7.i686.rpm openssl-devel-0.9.7f-7.i386.rpm ================================================ (without any particular request from me) and that the i686 version is somehow incompatible with the i386 version of other packages. In any case, I've tried various subterfuges, but have not succeeded in getting "yum update" to work on this machine. [It works OK on another machine with x86_64 distribution also updated from FC-3.] There are too many dependency errors to exclude all the packages involved. Any advice or suggestions gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
