[chef] Re: Forcing a downgrade/upgrade of an apt package

[Jacobo García < >]

Hi Brian,

I did not answer sooner (my apologies) because I had to re-create the tests environment, and then I figured it out what was going on.  

It was not a chef problem at all, it was an apt problem.

According to brightbox wiki[1] to "downgrade" to regular ruby you need to do some apt-pinning. The thing got a bit more complicated since there's a bug[2] in aptitude and I had to workaround it through chef (that meant more coding and testing) but now I am able to change back and forth from regular ruby to ree with easily.

Thanks for your time.

Can you provide the package related output from running chef with "-l
debug"? For example:

[Tue, 22 Feb 2011 17:31:02 +0000] DEBUG: Checking apt-cache policy for
libmysqlclient-dev
[Tue, 22 Feb 2011 17:31:02 +0000] DEBUG: Current version is 5.1.41-3ubuntu12.9
[Tue, 22 Feb 2011 17:31:02 +0000] DEBUG: Current version is 5.1.41-3ubuntu12.9

Note that due to CHEF-1276 [1] the second one is the Candidate version.
