[Synaptic-devel] Trouble with dependencies?

[Andreas Schmidt]

Hi,

I just noticed something which may be a bug in synaptic. Somehow,  
dependencies seem not to be resolved correctly. I just noticed that  
with the cron-package.

Synaptic shows there's an update from 3.0pl1-77 to  3.0pl1-82  
available. Among the dependencies for this package is this:

Recommends: exim | postfix | mail-transport-agent

"exim | postfix | mail-transport-agent" are also shown by synaptic 	 
in the Dependencies/Suggestions and Recommendations view.

I have postfix installed on my box. When I mark the package for update,  
synaptic wants do remove postfix and install exim instead. Unchecking  
the "Consider recommended packages as dependencies" box in the  
preferences dialogue takes care of that; nevertheless, synaptic should  
be able to recognize one of the alternatives already is installed.

(Some time ago, there was a similar problem with tiger. That package  
recommends sendmail or mail-transport-agent, but did not recognize  
postfix either, although that provides mail-transport-agent.)

Best regards,

Andreas
