A just ran the command yum -y -d 5 -e 10 update knowing thanks to "Red Hat Network Alert Notification Tool" (rhnant) that six updates are available: ethereal, ethereal-gnome, fam, fam-devel, initscripts, ppp. The output from yum enden in the following lines: nulist = 886 uplist = 6 newlist = 880 obsoleting = 0 obsoleted = 0 Updating fam Updating ppp Updating fam-devel Updating initscripts Updating ethereal Updating ethereal-gnome Resolving dependencies Updating: initscripts, i386 Not an install only pkg, adding to ts What means the final message? Checking with rpm, fam and ppp had the same version as before, not the version available according to rhnant. I then ran the exact same command, yum -y -d 5 -e 10 update, and this time the output appeard to reach the same point and to continue further: nulist = 455 uplist = 6 newlist = 449 obsoleting = 0 obsoleted = 0 Updating initscripts Updating ethereal Updating ppp Updating fam Updating fam-devel Updating ethereal-gnome Resolving dependencies Updating: initscripts, i386 Not an install only pkg, adding to ts Updating: ethereal, i386 Not an install only pkg, adding to ts Updating: ppp, i386 Not an install only pkg, adding to ts Updating: fam, i386 Not an install only pkg, adding to ts ... A few lines further down , yum stated to download the packages in question. What means "Not an install only pkg, adding to ts"? Why does yum stop prematurely in the first run succeed in the second? When I issue the command the second time, the first line of output is Unable to find pid This message also appear if I interrupt (^C) a hung yum, and I repeat the command. I suspect that there is a connection, indicating that the first run terminated without running some cleanup code. Regards, Enrique
