Re: [ros-users] New packages for Groovy

You should never do this (cf. [1])! Package versions as all version numbers
are only allowed to go up, not down. If you really need to downgrade a
package, you can add the old version number behind the new one, like
this: 1.7.4+rally1.6.2-s1395213230~precise, alternatively (in case you
messed up the version numbers) you can add a epoch [2]. Could you please
fix this, as it breaks updates?

Thanks!

Jochen
