It can still happen in another way, to those who use free but proprietary apps. Say you want Opera on an old machine that you haven't used for some time. You go to a browser it does have, but for some reason the default opera.com offers isn't what you want. You find what you do want, and opera.com asks whether you want the x86 or the 64-wide version. You don't happen to remember which one this machine is, nor an easy way to check (like uname -a). So you just download one. Rpm -ivh produces a bramble patch. Being by now an old hand, you notice that all the missing dependencies it announces are 64s. So you abort the install, go back to opera.com, and get the .rpm for a 32-bit machine. That works, slick as a whistle. In this example you have not solved the dependency hell. You have dodged it, partly by dumb luck (spotting those 64s), and partly by having enough general experience to recognize what they mean. A beginner who had gotten into it might easily've worked herself through the brambles into an electronic lake of burning brimstone before she hollered for help. -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User Remember I have precious (very precious!) little idea where up is. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
