According to what I gathered info wise, fppkg only supports one config 
dir. (it has some options, but not sure the IDE uses those)
So it does not work well for Lazarus multi install.

The IDE will work fine without it.
It' only needed if you need some of the few packages that are only avail 
via fppkg (though you can download them by hand anyway)

The one in your home folder (I don't have Linux path)...
On Windows it's in %APPDATA%\Local\FreePascal\fppkg

There are files like fppkg.cfg mirrors.xml packages.xml and some folders.

there is an fppkg utility in the fpc folder. (fppkg is part of fpc)

If you just run it
fppkg
it should create a config file (if none exists).
It wont say that it did, it just prints the help.
(could be that fpc needs to be in path)

It is a long time back since I last dealt with it (I now have it 
disabled...)

It is not about the lazarus version, but different fpc versions.
In my case (but maybe I was lucky) the older fpc didn't complain....

Anyway that is about what I remember from when I last fought with it....
Sorry, it's not much....
