Update wants to update lm_sensors: # yum -C check-update lm_sensors.i386 2.10.0-43.rhfc5.at atrpms lm_sensors.x86_64 2.10.0-43.rhfc5.at atrpms lm_sensors-devel.x86_64 2.10.0-43.rhfc5.at atrpms But it can't: # yum -d 1 update Error: Missing Dependency: libsysfs.so.1 is needed by package lm_sensors Question: Is there a way to tell yum to update everything that it can, and to ignore those packages which can't be updated at the moment? I ask, because this update, which I don't care about right now, was holding up all other updates. I worked around this by updating by hand and excluding the lm_sensors related packages. I know that I can manually add lm_sensors in as an exclude in yum.conf, but that isn't really what I want to do, because eventually I may want to arrange to update the package, and don't want it to be silently forgotten for now. Back to resolving the dependency. The FAQ: http://wiki.linux.duke.edu/YumFaq#Q6 says: "One relatively easy way to fix this is to remove whatever package "needs" the packages that are about to be upgraded/obsoleted and then reinstall that package after you have upgraded everything else. In the example, remove junit, upgrade, then reinstall junit" ---- Given my example, I presume that I need to arrange to remove lm_sensors along wiht the packages that depend upon it. Through trial and error, it seems this command will do the trick: # rpm -e --allmatches lm_sensors lm_sensors-devel net-snmp net-snmp-utils freeradius net-snmp-devel ethereal php-snmp freeradius-mysql (Is there a script generally available that calculates the transitive closure needed when removing a particular package? It would save a few steps.) That's a fairly long list of things, and I'm just a little worried that when I install the newer version of lm_sensors that some of these packages may not like the newer version. Is it usually the case that they'll happily accept the newer version? I realize that the version of lm_sensors in this case is outside the FC5 distribution, and is likely somewhat experimental. For that reason, I'm not particularly keen to update it, but would like to understand the mechanics of resolving the dependencies, so am running the example by y'all. Is this generally the approoach to follow? Is there any way to tell yum just to ignore things it can't update?
