How to install software for particular user? or for all User?

When someone installs a software package on Ubuntu with help of the package management programs (Software-Center, Synaptic, apt-get...) this software is available to all users.

If you want to install a program in a way, that it can be used only by one specific user you have to do specific actions that very much depend on the specific application.

There is one important segregation: When you want to use specific administrative programs, you have to be member of the admin group and must be allowed to issue the sudo command. A user who is not in the admins group and not allowed to use the sudo command can still try to use those programs, but after the first steps such program will end with an error message.

If you have specific questions, e.g. about a certain program that you want to have installed for just one user, do not hesitate to ask, we will try to help you further.

Hi, in linux (all distribution) only root user can be install the software (unless you gave more permissions to a specific user). If you haven't done this, on your Ubuntu Machine only root can install software.
if your idea is to give these permissions to a single user than root, you have to raise user privileges that can install. To do this you can see this guide:
