This question already has an answer here:
I am currently at 15.04. I want to upgrade to a stable version soon, but after I finish some projects I am working on every day. I assume these projects will take another 6-8 weeks, but my system is now complaining about system errors and that there are no software updates for this version.
I can still use my computer, but how long will it will take before this all comes crashing down? Do I have enough time to finish my projects, or should I update immediately?
