Installing on Debian 12 from our packages repository

At the moment only AMD64 binary packages are supported:

    $ curl | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/spectrumim.gpg
    # echo "deb [signed-by=/etc/apt/trusted.gpg.d/spectrumim.gpg] bookworm main" >> /etc/apt/sources.list.d/spectrum.list
    # apt-get install apt-transport-https
    # apt-get update 
    # apt-get install spectrum2 spectrum2-backend-libpurple spectrum2-backend-libcommuni

Installing on other Debian/Ubuntu-based distributions

You need to rebuild source libcommuni and spectrum packages from our source package repository:

    $ curl | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/spectrumim.gpg
    $ apt-get install devscripts fakeroot apt-transport-https
    $ echo "deb-src [signed-by=/etc/apt/trusted.gpg.d/spectrumim.gpg] bookworm main" | sudo tee /etc/apt/sources.list.d/spectrum.list
    $ apt-get update
    $ apt-get build-dep communi
    $ apt-get source communi
    $ cd communi-3.6.0 && DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -us -uc  && cd .. && sudo dpkg -i libcommuni*.deb
    $ apt-get build-dep spectrum2
    $ apt-get source spectrum2
    $ apt-get install libminiupnpc-dev libnatpmp-dev
    $ cd spectrum2-2.2.1 && DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -us -uc  && cd ..

When the compilation process has ended the .deb packages for libcommuni and spectrum will be generated in the current directory and can be installed with dpkg -i < filename.deb >.


  1. If you got gpg verification error, then dscverify can not find appropriate keystore, see for fix. This shouldn’t happened if you are install keys and build packages from the same account (Note, building doesn’t require root)

    Quick packaging with CPack

If you want to test latest changes and save time on full rebuild of all packages, you can quickly create a single package from usual build tree, like:

    # cpack -G DEB -D CPACK_PACKAGE_CONTACT="Your Name <[email protected]>" -D CPACK_PACKAGE_NAME="spectrum2-nightly" -D CPACK_PACKAGE_FILE_NAME="spectrum2-nightly" -D CPACK_PACKAGE_VERSION="2.1.x" -D CPACK_DEBIAN_PACKAGE_DEPENDS="libboost-all-dev (>= 1.49), libc6 (>= 2.14), libswiften2 | libswiften3, libcurl3, liblog4cxx10, libpurple0" -D CPACK_DEBIAN_PACKAGE_CONFLICTS="spectrum2, spectrum2-backend-libpurple, spectrum2-backend-swiften, spectrum2-dbg, libtransport2.0, libtransport-plugin2.0"
