You cocould try using -- skip-broken to work around the problem
You cocould try running: rpm-Va -- nofiles -- nodigest

Solution:
Yum install ruby-devel rubygems
Gem install rack
Gem install sqlite3-ruby
This is still a variety of failures, and later found that the ruby version automatically installed by yum is too low, re-install the ruby version later
Yum remove ruby

Forget the default password of oneadmin
Opennebula uses sha1 to encrypt the user password. Therefore, we use the sha1 encryptor to encrypt 123456 and obtain the encrypted string. Then, we log on to the database and record the user information in the user_pool table in the opennebula database, in addition, the data in the body field is the password encryption string of the corresponding user.
We use the encrypted string to replace the data in the body field of the username oneadmin column in The user_pool table.
Then modify the/var/lib/one/. one/one_auth file content: oneadmin: 123456
Now, you can log on with the password 123456.
