I started recently using Pd on Ubuntu and I have some struggles.
Now I'm using 0.49 Pd version.
After installing the external, i.e. mrpeach, I can open the help patch and use it.
But.. if I restart pd, creating a new file and try to create a packOSC object, pd can't create it. Then if I open the help file everything is ok and I can create the object in every new patch.
What's wrong? Never happend to me, neither on Debian or Windows or Mac.
The strange thing that's it's happening is that everything I save (externals and patches) are always locked. I'm not the owner of the file.
So I think that there is an error about permission and installing process
