Odroid XU3 Lite – unrar non-free missing

In case you own Odroid XU3 Lite with Ubuntu you might not have unrar in the system. Somehow apt-get won’t see such package.

There is unrar-free, but this is too immature and has non standard CLI API.

Here’s what you have to do – build it for yourself! :-)

wget http://www.rarlab.com/rar/unrarsrc-5.2.5.tar.gz
tar xfvz unrarsrc-5.2.5.tar.gz
cd unrar/
sudo cp unrar /usr/bin/unrar-nonfree
sudo rm /etc/alternatives/unrar #might fail, don't worry
sudo ln -s /usr/bin/unrar-nonfree /etc/alternatives/unrar

From now on, you have system wide unrar cmd available to use. And SABnzbdPlus won’t complain :-)

Raspberry PI arrived – setup howto


This is mainly a reference for myself how and what to install/configure on a fresh Raspberry PI

Hope it helps you too


Have a Raspberry PI

  • on a 8GB card download and install an image: Raspbian
  • Power on Raspberry PI
  • First time installation
    • via GUI: maximize hard drive
    • set GPU RAM to 16
    • enable SSH
    • setup static DHCP address on home router
    • setup another system user (thanks to this post) and make sure it can do `sudo` without password prompt
      • adduser foo
        echo "foo ALL=(ALL) NOPASSWD: ALL" >>/etc/sudoers
        userdel pi
    • add yourself to disk group
      • sudo vigr # find disk, add your username
    • setup SSH
      • sshkey-gen
        remote$ ssh-add foo@..
        remote$ ssh-copy-id foo@..
        vim /etc/ssh/sshd_config
        PermitRootLogin no
    • setup /etc/hosts
