Hello @telecast

It seems you don’t have the correct onedb_live file, did you update via public packages or compiling yourself?

Hello @ahuertas

By myself compiling by use this repo https://github.com/OpenNebula/packages
My steps:

```
git clone https://github.com/OpenNebula/one opennebula-X.Y.Z
cd opennebula-X.Y.Z
git checkout tags/release-X.Y.Z

# manual pages
cd share/man
./build.sh
cd ../../

# sunstone
cd  src/sunstone/public
./build.sh -d
export PATH=$PATH:$PWD/node_modules/.bin
./build.sh
rm -rf node_modules/
cd ../../../../

tar -czf opennebula-X.Y.Z.tar.gz opennebula-X.Y.Z/
cd packages/
./centos7.sh ../opennebula-X.Y.Z.tar.gz
```

It seams that function each_page is missing in pool.rb. Could you please check the file /usr/lib/one/ruby/opennebula/pool.rb and find the funcion each_page?

7

Yes you are right, I can’t find this function:

]# less /usr/lib/one/ruby/opennebula/pool.rb | grep each_page
]#
8

The changes were done in this commit. So check it and add the missing method.
