Install Fuerte over Electric

I am thinking to install Fuerte. I currently have Electric.

I would like to ask if I have to remove the Electric before doing so. If yes, how do I do that? If no, what will happen to those packages in Electric, which I expect will have duplicates in Fuerte? I have also rosinstalled a number of packages in my user folder (in user/ros), which was done with "rosinstall . /opt/ros/electric package.rosinstall". Do I have to do anything to these packages or can I continue to use them as they are (knowing that I will have to change some codes to work with new packages)?

Thanks in advance.

This was a similar question about upgrading from Diamondback to Electric, and pretty much everything from that answer is the same for upgrading from Electric to Fuerte. Basically, you can leave Electric installed, but you need to rebuild all of your source packages.

You could also look into overlays to see if that would help you more in your current situation.

Many thanks! The links are very useful. I wasn't aware of them. Well, I might have been doing overlays with rosinstall (am I?). Has rosws replaced rosinstall? Or are they two different things. My apology that I am still trying to comprehend this stuff.

As for the "recompile", I had been using rosinstall to install packages to my user/ros. Can I simply "recompile" them using "rosinstall . /opt/ros/fuerte package.rosinstall"?

rosws is part of the rosinstall package. It provides a command interface that many of us like for maintaining source overlays.

To recompile, you should either check out fresh copies of any source overlays (recommended), or do a make clean in every source package before rebuilding it.

Thanks for that important tip on make clean, joq.

  1. In my opinion, you don't have to remove the previously installed Electric(even you can actually remove it).
  2. In your folder user/ros, I would say, after installing the Fuerte, it won't affect the folder, even you might want to have a copy as backup.

Many thanks for the reply. I have many doubts at this point, however I shall go ahead and try it out to find out what I should exactly ask.
