[chef] Knife error uninitialized constant Chef::Knife::Ssh (NameError)

[David Montgomery < >]

Hi

For any knife command I am using, I am getting the below error.  If I
repeat the command 3-4 times it will then work.  I noticed after I ran
gem update fog

So, knife is now useless in a production env.  How do I resolve?
Again, this is for any knife command, not specific to the command I
used below.



 knife cloudstack server create 'role[nginx_server]'  .........
