Still the same problems I'm afraid. I read the release notes and followed them to the letter. I'm now seeing: Finished Dependency Resolution lvm2-2.02.46-8.el5.i386 from base has depsolving problems --> Missing Dependency: device-mapper >= 1.02.32-1 is needed by package lvm2-2.02.46-8.el5.i386 (base) mkinitrd-5.1.19.6-54.i386 from base has depsolving problems --> Missing Dependency: device-mapper-multipath >= 0.4.7-9 is needed by package mkinitrd-5.1.19.6-54.i386 (base) lvm2-2.02.46-8.el5.i386 from base has depsolving problems --> Missing Dependency: device-mapper-event is needed by package lvm2-2.02.46-8.el5.i386 (base) Error: Missing Dependency: device-mapper-multipath >= 0.4.7-9 is needed by package mkinitrd-5.1.19.6-54.i386 (base) Error: Missing Dependency: device-mapper-event is needed by package lvm2-2.02.46-8.el5.i386 (base) Error: Missing Dependency: device-mapper >= 1.02.32-1 is needed by package lvm2-2.02.46-8.el5.i386 (base) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest I've installed package cleanup and tried the suggested combinations, except the --skip-broken option. Any thoughts are appreciated. Rohan.
