Installation - 3 Upgrading From Fink 0.3.x
If you already have Fink 0.3.x installed, you can update your installation to 0.9.0 with the built-in 'selfupdate' command.
3.1 Updating The Package Manager
To update Fink, run the following command:
fink selfupdate
This will automatically update your existing Fink installation to use the latest package manager, and also update all essential packages. However, it will not update any other packages.
3.2 Getting tetex Sorted Out
If you are upgrading from a Fink release prior to 0.3.1, and you have tetex installed, you should run the command "fink remove tetex" before upgrading. (It may also be necessary to remove the packages which depend on tetex, such as lyx, before tetex can be removed.) Afterwards you can again install tetex and the other packages you removed.
3.3 Updating Packages
The above updating steps will not update the actual packages, they only provide you with the means to do so. The easiest way to get the new packages is to use the 'update-all' command:
fink update-all
This will bring all installed packages to the latest version. If you don't want to do this (it may take some time), you can update individual packages with the 'update' command.
