Hi
I have created a yum plugin there solves the problem with updates with
dependency problem there blocks from updating
your system.
Installation:
copy depcheck.py to /usr/lib/yum-plugins/
copy depcheck.conf to /etc/yum/ /etc/yum/pluginconf.d/
Usage:
Then the plugin is installed, i add a new option : '--depcheck' to yum.
Ex.
#yum --depcheck update
Then the option is used, then the plugin will check each update for
dependency problems, and remove the ones from the transaction there has
problems.
Try it out and let me know if there is any problems. I works i both yum
2.6.1 & 2.9.5.

# A plugin for yum, there checks each packages in the transaction
# for depency errors and remove package with errors from transaction
#
# the plugin will only be active if yum is started with the '--depcheck'
# Option.
#
# Ex.
# yum --depcheck install foo
