When Ubuntu 10.04 was released it represented the most modern incarnation of Canonical’s premier Linux desktop distribution. However not all things were better in this release. For myself I immediately noticed a problem while trying to install the gnustep-devel development libraries for GNUstep and Objective-C. I was greeted with this oh so lovely error message:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help resolve the situation:
The following packages have unmet dependencies:
gnustep-devel: Depends: gorm.app but it is not installable
E: Broken packages
So essentially I was left with the following choice: install the missing Gorm.app package from the repository (which wasn’t there) or don’t install gnustep-devel. Thankfully it was pointed out to me that I could perhaps see if the package still existed in the Debian repository instead. So off to http://www.debian.org/distrib/packages I went and after a quick search I found what I was looking for! I recalled reading somewhere that Ubuntu synchronizes with Debian testing (A.K.A. squeeze) at the start of every round of development, so I figured that would be the best package to grab. A short download and install later Gorm.app was finally on my system. With the dependencies now met it was a breeze to install the rest of the development files using a simple
sudo apt-get install gnustep-devel
And there you have it. By installing a single package from the Debian repository you too can get around the problem. For reference I have also filed a bug report with Ubuntu at Launchpad here.
