I installed another Ubuntu on Virtual Machine and after installing VI Package Manager I had the same problems that happened on my previous Ubuntu. I guess this installation (or things I did in order to be able to install) changes the permissions of /tmp somehow. Now that I noticed this, I installed array library and they are installed but not on the palette. I have the array.llb somewhere under user.lib.Since this library is already installed, if I install the latest version of dynamic palette manually I guess it should show everything that is already installed?
