ubuntu 14.04 apt-get update 无法找到arm package

        楼主经历了几天苦逼的日子(反复给电脑刷ubuntu 14,.04系统,为tx1刷系统及安装cuda)之后,终于又迎来了新的问题!

        在ubuntu 14.04下,使用sudo apt-get  update 命令会出现错误,电脑莫名奇妙的和arm 64 打架了!

medivh@DT-AND-11430203:~$ sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa This PPA is an alternative to toolchain released at https://launchpad.net/gcc-arm-embedded. The source codes for both are same. Currently supports Ubuntu 10.04/12.04/14.04/14.10 32 and 64 bit. Detailed explanations to Launchpad PPA can be found at https://help.launchpad.net/Packaging/. That website explains how a PPA is set up and how to add existing PPA and install software from it. Here are quick steps to install toolchain from this PPA on Ubuntu before 14.04: Step1: Inside Ubuntu, open a terminal and input "sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa" Step2: Continue to input "sudo apt-get update" Step3: Continue to input to install toolchain "sudo apt-get install gcc-arm-embedded" To remove installed toolchain, just input "sudo apt-get remove gnu-arm-embedded". To update the toolchain, just repeat above step2 and step3. If it reports error message of conflict to gcc-arm-none-eabi, which is likely if upgrading from 4.x to 5+, please uninstall it first with: "sudo apt-get remove gcc-arm-none-eabi" Questions should be asked at https://answers.launchpad.net/gcc-arm-embedded Bug can be filed at https://bugs.launchpad.net/gcc-arm-embedded/+filebug. It is highly encouraged to ask question first before filing a bug. More info: https://launchpad.net/~team-gcc-arm-embedded/+archive/ubuntu/ppa Press [ENTER] to continue or Ctrl-c to cancel adding it.
