Greetings. We've just installed what we believe to be SL 3.0.3 for AMD on a dual-Opteron system here. (We "believe" because the manufacturer, Penguin, sent us the CD's; we didn't download the ISO's ourselves. It certainly LOOKS like 64-bit software, and we did reinstall the OS from scratch ourselves.) We have a number of Opteron systems, but the others are running RHEL. There seem to be 36 "duplicated" packages on this system. For instance: [root]# rpm -qa | grep samba-3.0.9-1.3E.1 samba-3.0.9-1.3E.1 samba-3.0.9-1.3E.1 We also see the same general kinds of duplication on a dual-Opteron system running RHEL 3.0.3 WS. Perhaps this reflects the installation of both 32-bit and 64-bit versions of some packages? (But I don't know why we'd see that with Samba, for instance.) In any case, we seem to be able to use yum to apply updates to the system, but using apt-get gives us pages and pages of error messages. See the appended for a sample of both. Thus, I have two questions: (1) why, exactly, do we have the duplicated packages? (2) Why does yum work but apt not? Thanks. - Mike Appendix: apt-get failure, yum success ====================================== [root]# apt-get update Get:1 ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm release [1064B] Fetched 1064B in 0s (1419B/s) Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/os pkglist Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/os release Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/updates pkglist Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/updates release Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/contrib pkglist Hit ftp://ftp.scientificlinux.org 303/x86_64/apt-rpm/contrib release Reading Package Lists...
