apt-get upgrade safe?

[Robby]

I have a ubuntu vps that hosts a couple rails applications. Ruby/git/passenger/nginx were installed outside of apt-get but their dependencies weren’t. I also installed MySQL through apt-get.

Think its safe to run apt-get upgrade? I’ve been doing so and it hasn’t caused any problems so far but what do you think? Recipe for disaster?

apt-get can only manage things it installed, so upgrading might cause breaking changes with programs it doesn’t know about.

This is not to say I don’t recommend keeping ubuntu up-to-date. I certainly do. Why did you not use apt-get to install those programs in the first place? Ruby, git and nginx are all in the default repos. If by “passenger” you mean Phusion Passenger, they have an apt repo too.

Get another VPS set everything up correctly, then move the codebase and test. Hopefully your apps are not too complex, you could write some tests and you can run those same tests when you move.

You could use something like Vagrant and VirtualBox to run everything locally as well.
