#In Debian / Ubuntu / LinuxMint / ElementaryOS:
sudo apt-get install android-tools-adb android-tools-fastboot

#In Fedora / Centos :
sudo yum install android-tools 


记得root 
evan@myxps:~$ fastboot  devices

evan@myxps:~$ sudo fastboot  devices 
PM1LHMA792000781	fastboot

方法2

On Linux

    Download the Linux zip from Google.
https://dl.google.com/android/repository/platform-tools-latest-linux.zip

cat /etc/profile

 if [ -d "/home/evan/adb-fastboot/platform-tools" ] ; then
     export PATH="//home/evan/adb-fastboot/platform-tools:$PATH"
    fi



这些不太行 
    Extract it somewhere - for example, ~/adb-fastboot.
    Add the following to ~/.profile:

    if [ -d "$HOME/adb-fastboot/platform-tools" ] ; then
     export PATH="$HOME/adb-fastboot/platform-tools:$PATH"
    fi

    Log out and back in.

   You may also need to set up udev rules: see this repository for more info.
