Firstly, thanks for your response. I know, as you say, that the problem will probably sort itself out shortly. I was really more interested in the logic behind the problem. But I confess that I am still baffled by this logic. Let me recall what I did: --------------------------------------- [tim@rose ~]$ sudo yum remove iptstate ... [tim@rose ~]$ sudo yum install iptstate ... --------------------------------------- No dependency problem. But now --------------------------------------- [tim@rose ~]$ sudo yum update --> Running transaction check --> Processing Dependency: libnetfilter_conntrack.so.1 for package: iptstate-2.2.1-5.fc11.i586 ... Error: Missing Dependency: libnetfilter_conntrack.so.1 is needed by package iptstate-2.2.1-5.fc11.i586 (installed) --------------------------------------- But now it seems to say that iptstate requires libnetfilter_conntrack. So why didn't it say that before when I yum-installed iptstate? Surely when you yum-install a package yum checks that you have all the required dependencies? It's only a tiny point; yum is a great tool, in my view, and one of the best things about fedora. But it is a bit confusing when a program seems to contradict itself. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
