Installation image

Download the image

System images are typically distributed as ISO files (*.iso filetype), but may also come as a compressed system image (e.g. FileName.xz).

The first step to install PureOS is to download and verify the integrity of the PureOS hybrid live/install ISO image.

Download PureOS and select the latest hybrid install/live PureOS ISO image.

Verify the image

When the download is complete, make sure to check that the sha256 checksum hash matches to the one calculated for your downloaded ISO. This ensures that the download completed successfully and the file is not corrupted. You can calculate the checksum using sha256sum utility (run this in your terminal):

sha256sum ~/Downloads/pureos-8.0-gnome-live_20180904-amd64.hybrid.iso

(provided that you downloaded the image to your Downloads folder).

Note

The ISO image date string (20180904) may differ.

You can alternatively use a graphical utility called GtkHash, which may be obtained from the Software center:
