So, after googling 10 seconds, I found this which suggested to lock some packages to avoid them being upgraded automatically by Ubuntu. Exactly what I needed! In order to do so, go in Synaptics, find the package you want to lock (in my case libsvn1 and subversion), highlight it and then go in Packages > Lock.

Since then, it’s working perfectly now!

When I was trying to access SVN features from within a project which files came from my Ubuntu 8.04 laptop, it was working. However, checking out a project on my new Ubuntu 9.10 was causing EasyEclipse to not be able to recognize the project as an SVN project. When I was right-clicking any folder inside that project and selecting the Team item, there was only Apply Patch… and Share Project. I was missing all the usual: Commit, Update, Branch/tag, etc…

I googled a lot but did not find any solutions at first. I installed Eclipse alone, but it would not even start… I installed Eclipse from Synaptic, same thing, it would not start. It was only displaying the splash-screen and then it disappeared. Nothing else. I even installed Zend Studio, and I was getting the exact same problem: the Team contextual menu item was not displaying the SVN features.

I was starting to feel a little bit helpless. My only workaround was to develop with EasyEclipse but to commit and update via the command line. Doable, but not painless…

I googled one last time and after many many readings, I stumbled on someone hinting that there might be a problem between Subclipse and Subversion itself. It made me think. Why were the projects coming from Ubuntu 8.04 were working and the newly checked out projects from Ubuntu 9.10 were not. The hypothesis that there could be a conflict between Subclipse and Subversion started to make sense…

So I went on Ubuntu 8.04 Synaptic and checked the version of Subversion. I did the same on Ubuntu 9.10. They were of course not the same version. So it seemed that projects checked out with subversion from Ubuntu 8.04 were compatible with Subclipse, but not the ones checked out with Ubuntu 9.10. So the solution: uninstall subversion and reinstall the previous version, the one installed on Ubuntu 8.04! So here are the steps I had to do:

• Uninstall subversion
• Uninstall libsvn1 (a dependency of subversion)
• Install libsvn1
• Install subversion-hardy

And now, everything works !!
