Software Installation Non-Root User – How to Install Programs Locally Without Sudo Privileges?

not-root-usersoftware installation

Assume I have ssh access to some Ubuntu server as user and I need some not system tools to be installed for convenience (mc, rtorrent, mcedit). I do not want to bother admins for these small programs.

Is there a way to install them (make them run) without using something like sudo apt-get install?

Best Answer

  1. Compile and install into ~/bin (and edit your .bashrc to set the PATH to include it). libraries can similarly be compiled and installed into ~/lib (set LD_LIBRARY_PATH to point to it), and development headers can be installed into e.g. ~/includes.

  2. Depending on the specific details of the programs you want to install and the libraries they depend upon, you can download the .deb files and use 'dpkg-deb -x' to extract them underneath your home directory. You will then have a lot of "fun" setting the PATH, LD_LIBRARY_PATH, and other variables. The more complex the program or app you're installing the more fun you'll be up for :)

    You will, of course, not be able to install setuid binaries this way - they'll install but (since you don't have permission to chown them to root or set the setuid bit on them) they'll just be normal binaries owned by you.

    Similarly, daemons and system services that expect to be running as a certain UID or have the ability to change uid, or expect files to be in /etc rather ~/etc and so on aren't likely to work well, if at all.

  3. Most sysadmins would consider mc and mcedit to be "mostly harmless", innocuous programs.

    Very few, however, would consider installing a torrent client to be harmless, especially if they have to pay for bandwidth or end up being legally liable. Most sysadmins would probably not be entirely happy for end-users to be installing such software without permission. They may say "sure, go ahead, knock yourself out" or they may not...but you should ask about anything that may cause problems for the owners/administrators of the machine.
