Hello there,

I’m checking if I can upgrade safely from CentOS6.5 to 6.6 using yum, and here’s what it says:

=====================

Not found You could try using –skip-broken to work around the problem You could try running: rpm -Va –nofiles –nodigest
=====================

Those packages depend on mpich2.x86_64:

boost-graph-mpich2 x86_64 1.41.0-18.el6 @base 440 k boost-mpich2 x86_64 1.41.0-18.el6 @base 353 k boost-mpich2-python x86_64 1.41.0-18.el6 @base 44 k hdf5-mpich2 x86_64 1.8.5.patch1-7.el6 @epel 6.8 M
mpich2-devel x86_64 1.2.1-2.3.el6 @base 6.8 M

I presume it’s the dep from hdf5mich from epel which is blocking.. Any hint about what I could do now?

Regards,
