I am trying to install the UrBackup Server on my Raspberry Pi running Raspbian 9 (stretch) (fresh install).

I followed the steps described in the installation notes:

wget https://hndl.urbackup.org/Server/2.2.8/urbackup-server_2.2.8_armhf.deb
sudo dpkg -i urbackup-server_2.2.8_armhf.deb
sudo apt install -f

However, this resulted in the following error:

chown: missing operand after ‘urbackup:urbackup’

Here is the full trace:

How can I install UrBackup Server?


You need to compile the UrBackup Server yourself. Follow these steps to install from sources, basically described in the documentation:

  1. Tidy up the faulty installation attempt to prevent further errors while using apt-get:

    sudo dpkg -r urbackup-server
  2. Download the UrBackup Server source package

    wget https://hndl.urbackup.org/Server/2.2.8/urbackup-server-2.2.8.tar.gz
  3. Extract and navigate to the folder

    tar xf urbackup-server-2.2.8.tar.gz
    cd urbackup-server-2.2.8/
  4. Configure

  5. Make, do not run multiple threads (make -j 4), this might lead to errors, see below. This may take a while (20-30 minutes):

  6. Install

    make install
  7. Add UrBackup to the system startup

  8. Auto-mount USB drive

Some sidenotes for these steps if errors occur:

  • configure: error: Your system lacks of libcurl >= 7.20.0

    • run sudo apt-get install libcurl4-gnutls-dev to install the missing library
    • run ./configure again.
  • Crypto++ not found. Please install (cryptopp-devel/libcrypto++-dev) or run configure with --enable-embedded-cryptopp.

    • run sudo apt-get install libcrypto++-dev to install the missing library
    • run ./configure again.
  • g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-6/README.Bugs> for instructions.

    • Run make instead of make -j 4
