Hello

I have a problem for executing : cap deploy

I already did some migration without any problem, but since few days  
(after debian’s update) I can’t use cap deploy I have this message :

:~/ERP/Administration$ cap -v deploy  
\*\* transaction: start  
Password:  
\*\*\* [update\_code] transaction: rollback  
\*\* [update\_code] exception while rolling back:  
Net::SSH::AuthenticationFailed, username  
authentication failed for `username’

My password is ok  
and normally I don’t use ssh : ssh\_options[:paranoid] = false (in  
deploy.rb)

I use capistrano 1.4.2

Does anybody have an idea ? how can i check the problem ??

Thanks in advance
