Zero Install

the antidote to app-stores

Install from Source

This is the newer OCaml version of 0install. There is also an older pure Python version. The OCaml version is completely backwards compatible with the Python version.

Name 0install
Maintainer Thomas Leonard
License GNU Lesser General Public License
SCM GIT repository

If you are looking for a package or the generic binaries, try the main downloads page.

Instructions

Download the latest .tar.bz2 archive from the SF.net download page (and the corresponding .sig file if you want to verify it), or using wget:

$ wget https://downloads.sf.net/project/zero-install/0install/2.7/0install-2.7.tar.bz2
$ wget https://downloads.sf.net/project/zero-install/0install/2.7/0install-2.7.tar.bz2.sig

Check that the signature is correct using GPG (this also ensures that GPG is installed correctly). You'll need my GPG key, which you can download and import using --recv-key (or manually):

$ gpg --recv-key --keyserver pgp.mit.edu CA74D8BA
$ gpg 0install-2.7.tar.bz2.sig
gpg: Signature made Sun 25 May 2014 11:24:01 BST using RSA key ID CA74D8BA
gpg: Good signature from "Thomas Leonard <XXXXX@gmail.com>"
gpg: Good signature from "Thomas Leonard <XXXXX@users.sourceforge.net>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: DA98 25AE CAD0 8975 7CDA  BD8E 0713 3F96 CA74 D8BA

The warning is just to tell you that you haven't yet established that the key really belongs to me (ultra-paranoid users will now cross-check the finger-print using some other source of information).

You'll probably need to install some OCaml dependencies before you can build. See the README for details. You should then extract the archive, change directory inside it and build:

$ tar xf 0install-2.7.tar.bz2
$ cd 0install-2.7
$ make

Installing normally Installing without root access

For a normal install, either su to root, install, and exit from root, or use sudo:

$ sudo make install

If you don't have the root password, use this command. You'll need to make sure that ~/bin is in $PATH in this case.

$ make install_home
$ export PATH=$HOME/bin:$PATH

Logging out and back in again will ensure $PATH and the Applications menu get updated correctly, on Ubuntu at least.

You now have a new 0install command...
