Packages

Skywire is currently released for multiple OS:

  • MacOS (offical)
  • Debian (offical)
  • Arch (community)

Debian package

  1. In order to create the Skywire debian packages, make sure you are running a debian based distro and install the following packages
$ sudo apt install devscripts binutils-i686-linux-gnu binutils-aarch64-linux-gnu binutils-arm-linux-gnueabi dh-systemd build-essential crossbuild-essential-armhf gpg dpkg-sig
  1. Make sure you make the packaging script exectuable:
$ sudo chmod +x ./scripts/package_deb.sh
  1. Symlink the binary:
$ sudo ln -s arm-linux-gnueabi-strip /usr/bin/arm-linux-gnu-strip
  1. To sign the debian packages, add both the public and secret key if not already. Follow this guide for more info.
$ gpg --import ~/mygpgkey_pub.gpg
$ gpg --allow-secret-key-import --import ~/mygpgkey_sec.gpg
  1. Check if it is added correctly:
$ gpg --list-keys
  1. Run the packaging script. Make sure the eamil and full_name is the same as the key in gpg --list-keys: (NOTE: the email should be the same as the email of the key you are sigining with)
$ ./scripts/package_deb.sh 0.4.0 some@mail.ru full_name

The first argument is a package version. The debian package should be created after a release has been made in github.com/skycoin/skywire and the version should follow the tag defined in the skywire repo.

During its work script will create packages for the following architectures:

  • amd64
  • i386
  • arm
  • arm64
  • armhf

For each architecture a changelog file will be created for a package and will be opened with the editor. Apply needed changes and save it.

The script will complain that there's no original code tarball. Ignore the warning by pressing y.

Once the script finishes, you'll see a deb directory in you current folder. This is where the finished packages are. Put these to /var/www/repos/apt/debian on the apt server and remove the old packages there.

  1. To sign the packages use:
    (NOTE: the email should be the same as the one used in 6. as well as the email of the key you are sigining with)
$ ./scripts/sign_deb.sh some@mail.ru

This will sign all packages.

  1. To verify the signature of a single package use:
$ dpkg-sig --verify ./deb/skywire_0.4.0-1_amd64.deb
Processing ./deb/skywire_0.4.0-1_amd64.deb...
GOODSIG _gpgbuilder 9A86A72D257E9EEAD3CE6ADDCC2026E6F21CEDA7 1620395902
  • If the package isn't signed, then the output will be NOSIGN.
  • If there is some error, it will be BADSIG.
  • If the package is signed, then the output will be GOODSIG. Followed by who signed the package _gpgbuilder and then the keyid of the key that the package is signed with 9A86A72D257E9EEAD3CE6ADDCC2026E6F21CEDA7 and lastly the epoch time of when it was signed 1620395902. To verify that the correct key was used for the signing, compare the keyid with the correct keyid from gpg --list-keys.
  1. To remove old packages from the repo, cd to /var/www/repos/apt/debian and use:
$ reprepro remove stretch skywire

This should be repeated for all needed debian releases.

  1. To add new packages to the repo, from the /var/www/repos/apt/debian use:
$ reprepro includedeb jessie ./skywire_0.4.0-1_amd64.deb

This should be repeated for all needed debian releases and built packages.

Verification and download by users

  1. Import the public key
$ wget -O - http://subdomain.skycoin.com/public-gpg.key | sudo apt-key add -
  1. Add repo to sources.list
$ deb http://subdomain.skycoin.com/ skywire main
  1. Run
$ apt-get update
