没有可用的软件包 ia32-libs，但是它被其它的软件包引用了。
这可能意味着这个缺失的软件包可能已被废弃，
或者只能在其他发布源中找到
然而下列软件包会取代它：
  lib32ncurses5 lib32z1

E: 软件包 ia32-libs 没有可安装候选 

9. ubuntu 下安装旧32位库 ia32-libs方法

在64-bit机器上运行32-big的应用程序是，需要安装ia32-libs库 下载ia32-libs.tar.gz（下载地址：http://www.uuuwg.com/user/other/61NziUd2T）

接着对“ia32-libs.tar.gz” 进行解压，解压完成之后进入相应的目录，此时你会发现有三个deb文件，执行以下命令对三个安装包进行安装。

sudo dpkg -i lib32asound2_1.0.25-3ubuntu3.2_amd64.deb

sudo dpkg -i lib32v4l-0_0.8.8-4_amd64.deb

sudo dpkg -i ia32-li

10. Linux minicom

Minicom is the serial tool that supports wide range baud rate.

Install minicom:

   sudo apt-get update
   sudo apt-get install minicom

Plug in the USB to TTL cable, kernel `dmesg | tail` should show the following device:

   [1036835.654076] usb 1-6.4.3: new full-speed USB device number 103 using xhci_hcd
   [1036835.755730] usb 1-6.4.3: New USB device found, idVendor=0403, idProduct=6001
   [1036835.755732] usb 1-6.4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
   [1036835.755733] usb 1-6.4.3: Product: USB <-> Serial
   [1036835.755734] usb 1-6.4.3: Manufacturer: FTDI
   [1036835.756728] ftdi_sio 1-6.4.3:1.0: FTDI USB Serial Device converter detected
   [1036835.756750] usb 1-6.4.3: Detected FT232BM
   [1036835.757195] usb 1-6.4.3: FTDI USB Serial Device converter now attached to ttyUSB0

/dev/ttyUSB0 is our device here.

Setup minicom

First add current user to plugdev group to use minicom without sudo or root.

   sudo usermod -a -G plugdev $USER

Edit your ~/.bashrc and add the following line with some default parameter

   alias minicom='minicom -w -t xterm -l -R UTF-8'

Login to a new terminal to take effect.

Create and edit file ~/.minirc.rockpiE, add the following content:

   pu port             /dev/ttyUSB0
   pu baudrate         1500000
   pu bits             8
   pu parity           N
   pu stopbits         1
   pu rtscts           No

Now run minicom rockpiE to use the config above and connects to the ROCK Pi E serial console.
