For the 1st time, we successfully had distro-info, Markdown, Pygments, PyGObject installed, but failed to install pycups. For the 2nd time, after libcups2-dev had been installed from Ubuntu repository, we had pycups installed successfully.
However, we still have one LAST issue: why distro-info is still oudated? ^_^ Can anybody give me an explanation?

Skill 15 - Run gdb with user root
Create a script called gdb in e.g. my home directory, containing: pkexec /usr/bin/gdb "$@"
make it executable
modify the launch.json in VSCode to call the script (obviously change username accordingly) by adding miDebuggerPath:
➜ pip list --outdated WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Therefore, python -m pip is used instead:

Hello, everybody. I’m now back in ShenZhen, China, and testing several types of Single Board Computers. I’ve got to say: Made In China is amazing. Banana Pi M3 is a SBC with AllWinner A83T ARM CPU, which is also of credit-card size. Some detailed features can be found on the open source technical supporter Sunxi. Please pay attention to the following key points:
PART A: Install Ubuntu Desktop Built By Armbian onto Banana Pi M3
1. Download Armbian Ubuntu Desktop for Banana Pi M3
We FIRST go visiting the website https://www.armbian.com/bananapi-m3/ and click Armbian Bionic icon, a file named Armbian_5.83_Bananapim3_Ubuntu_bionic_next_4.19.38_desktop will be automatically downloaded.

PART B: SSH Into Armbian, Update & Upgrade, Network Configuration, Locale Configuration
NOTE: Whenever you met some unsolvable issue after you boot into Armbian, please use the command armbianmonitor -U to log the issue.
1. SSH Into Banana Pi M3
We now unplug the TF card from the host and put it into the Banana Pi M3, Armbian Ubuntu Desktop boots successfully. The default username and password are respectively: root and 1234. In our case, Banana Pi M3 is connected to a network cable first, and it’s NOT hard for us to get the IP address of Banana Pi M3 by using command line nmap (Details can be checked via Google). After setting up a NEW user as well as password by following the previous blog Install Armbian Ubuntu Desktop onto Banana Pi Pro, you should be able to log into Banana Pi M3 with account root:
