"yum update" won't work for me on one computer because it complains that up2date (an ancient package) cannot be updated. For some reason "yum --exclude=up2date* update" does not seem to make any difference: ---------------------------- [root@alfred tim]# yum --exclude=up2date* update ... Running rpm_check_debug ERROR with rpm_check_debug vs depsolve: Package up2date needs python(abi) = 2.4, this is not available. Complete! ---------------------------- There has been no mention of up2date in the transaction except for this one. So I don't understand why this package was mentioned at all. I cannot remove it with "rpm -e": ---------------------------- [root@alfred tim]# rpm -e -vv --nodeps up2date ... + /etc/rc.d/init.d/rhnsd stop + /sbin/chkconfig --del rhnsd error reading information on service rhnsd: No such file or directory D: erase: waitpid(15510) rc 15510 status 100 secs 0.016 error: %preun(up2date-4.4.23-4.i386) scriptlet failed, exit status 1 ----------------------------
