Hi all,

I’m having a bit of a problem with installing ruby on rails using gem  
on Ubuntu server. For some reason, it tells me that the actionmailer  
is in an invalid format:

chris@gumshoe:~/rubygems-0.9.4$ sudo gem install rails  
Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org)  
Install required dependency rake? [Yn]  
Install required dependency activesupport? [Yn]  
Install required dependency activerecord? [Yn]  
Install required dependency actionpack? [Yn]  
Install required dependency actionmailer? [Yn]  
ERROR: While executing gem … (Gem::InstallError)  
invalid gem format for /usr/lib/ruby/gems/1.8/cache/  
actionmailer-1.3.3.gem

Any idea what I’m doing wrong here?

Hmmm, I haven’t installed Rails on Ubuntu Server yet, but it installed  
fine for me on my development (feisty desktop) machine.

I will note that installing as a gem is the way to go. The apt-get  
package for ubuntu is guaranteed to cause you problems at sooner or  
later.
