I had a ton of apps installed on my Fedora VM, and it took about half an hour for yum to chug through the list and reinstall them all. The only reason this method would not work, is if you install a bunch of apps using non standard methods, i.e. source tar.gz files, or other binary tar.gz files, and so on. If you install all (or even most) of your apps using RPMs, and better yet using yum (and not just random RPMs downloaded off the net), the rpm list method will work. > > >I am normally a Debian/unstable guy and to me "releases" are an alien > >concept.

I have had complex installs myself, and I used to do the upgrade path. It worked OK for the most part, but there were almost always issues. Now I have decided it is less headache to do a clean install, and just feed the rpm list to yum and let it chug. > As for software to get a list of installed apps, I have done that.

When it is done, voila, all your apps are reinstalled. It doesn't take weeks, it takes less than an hour (for me anyway, and I had about 1300 new apps beyond the standard live install image). It doesn't have to be readable by a person, just by yum ;) Though of course it is readable, if you feel like going through it all... This also only works well if you strip out the version numbers, and feed it only the package names. Otherwise you will run into dependency issues and so forth. > My upgrade from Fedora 11 to 13 is now complete except: > > * Can't get VirtualBox to launch.

Can't help with Praat... As for the python, have you tried uninstalling all four at the same time (as in, using rpm -e python-[x,y,z,a] on the command line), then reinstalling?
