You could try using –skip-broken to work around the problem
You could try running: rpm -Va –nofiles –nodigest
Actually my OS RHEL by default has python2.7 but ambari needs python2.6, So i had to change it 2.6 version. Then i got this error. I tried to installing individual lib rpm files, but thats not working. Any help on this would be great.
