[one-users] Cannot contact server: is it running and reachable?

[kenneth at apolloglobal.net]

Hi, 

I tried manual install of nokogiri. 

user at cloud-node1:~$ sudo
gem install --no-ri --no-rdoc nokogiri 
ERROR: Error installing
nokogiri:
 nokogiri requires Ruby version >= 1.9.2. 

I installed
ruby1.9.1-full before. Then i installed ruby1.9.3 and tried again with
the same result. There are no ruby 1.9.2 package in ubuntu 12.04
repository. 

Any more idea? 

Thanks,
Kenneth

machine, the notification still appears.

Although the notification appears, all features (as far as my testing
go) are working as expected. No errors yet.
