Bellow installation procedure uses only command line approach, because this is the simpler way to follow instructions just by copy-pasting the commands in terminal. This instructions are tested with the currently supported versions of Debian and Ubuntu.
This same procedure can be used with any system using deb packages (Mint, Raspbian, …)

This use a script with all the required command to setup the repository,

1. Copy and paste this command to a terminal to install the repository:

   bash <(wget -qO- https://raw.githubusercontent.com/pchev/skychart/master/setup_skychart_deb.sh) 

   Be sure to select the Beta version because this program is in beta version only.
   At this point you can install the program using the Software Center or continue using the command line with the instruction below.

2. Update repository:

   sudo apt update

3. Install CCDciel:

   sudo apt-get install ccdciel

See also the list of the optional dependencies to install to take full advantage of the software.

To open DSLR raw files you need the library libpasraw to interface with LibRaw.
Unfortunately the LibRaw programming interface is not stable across LibRaw version, so libpasraw must be build specifically for your system or it not work.

For Ubuntu you can simply install libpasraw from this PPA:
https://launchpad.net/~pch/+archive/ubuntu/ppa-skychart
then install with sudo apt-get install libpasraw

For a few other system you can find a package at:
https://github.com/pchev/libpasraw/releases

For other system you need to compile and install libpasraw from source after installing the libraw-dev package. See https://github.com/pchev/libpasraw/blob/master/README.md

As a last resort you can install the libraw-bin or dcraw package, but this is less performant as it need to work with temporary files.
