https://askubuntu.com/questions/1091653/how-do-i-disable-network-manager-permanently
For Ubuntu 18.04.1 LTS with GNOME desktop purging network-manager package will also purge ubuntu-desktop and gnome-control-center (essential part of GNOME desktop). So it is not an option.
Here you should disable NetworkManager service (as you have already done):
sudo systemctl stop NetworkManager.service
sudo systemctl disable NetworkManager.service
and three more services:
sudo systemctl stop NetworkManager-wait-online.service
sudo systemctl disable NetworkManager-wait-online.service
sudo systemctl stop NetworkManager-dispatcher.service
sudo systemctl disable NetworkManager-dispatcher.service
sudo systemctl stop network-manager.service
sudo systemctl disable network-manager.service
service network-manager stop
systemctl disable network-manager
service NetworkManager-wait-online stop
systemctl disable NetworkManager-wait-online
service NetworkManager-dispatcher stop
systemctl disable NetworkManager-dispatchersystemd-resolve --status

六、DRBL install
1.wget -q http://drbl.nchc.org.tw/GPG-KEY-DRBL -O- | sudo apt-key add -
2.vi /etc/apt/sources.list
----------
如果您的套件是Ubuntu Bionic (18.04):
----------
deb http://free.nchc.org.tw/ubuntu bionic main restricted universe multiverse
deb http://free.nchc.org.tw/drbl-core drbl stable
3.apt-get update
4.apt-get install drbl
5.drblsrv -i
6.drblpush -i
準備 mac address 檔

七、系統安裝後的調整
1.安裝字型（系統預設：/usr/share/fonts/字型檔放這（目錄亦可）
2.安裝 字型 （ 使用者： /home/使用者家目錄/.local/.fonts/ 字型檔放這
3.注意字型檔安權限（系統預設，給全體使用者使用時644）
4.應用程式安裝
Thonny is a simple IDE specially designed for beginners. It has simple and easy use user interface with some basic features like debugger, code completion, etc. Thonny comes loaded with Python 3.6 built out of the box which requires simple installer to get started with Python programming.
八、效能測試
1.網路卡效能測試
Intel® 乙太網路伺服器介面卡 I350-T4 X 2
九、其它
1.「錯誤回報」Remove “System Program Problem Detected” Messages From Ubuntu
To disable the service, first edit the /etc/default/apport file:
Then change enabled=1 to enabled=0:
# set this to 0 to disable apport, or to 1 to enable it
# you can temporarily override this with
# sudo service apport start force_start=1
enabled=02.snap 軟體安裝
註：由snap 安裝的軟體無法在 DRBL Client 中執行

2-1.Where is a snap stored and how can I change that?
https://forum.snapcraft.io/t/where-is-a-snap-stored-and-how-can-i-change-that/3194
By default they are in /var/lib/snapd/snaps
2-2.Add a Snap Icon to the Desktop Ubuntu 16.04
https://askubuntu.com/questions/800685/add-a-snap-icon-to-the-desktop-ubuntu-16-04

3-1.How to Enable /etc/rc.local with Systemd
https://www.linuxbabe.com/linux-server/how-to-enable-etcrc-local-with-systemd
1、建立rc-local.service文件
sudo vi /etc/systemd/system/rc-local.service
2、將下列內容復制進rc-local.service文件
[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
[Install]
WantedBy=multi-user.target
3、創建文件rc.local
sudo vi /etc/rc.local
4、將下列內容復制進rc.local文件
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo "看到這行字，說明添加自啟動腳本成功。" > /usr/local/test.log
exit 0
5、給rc.local加上權限
sudo chmod +x /etc/rc.local
6、啟用服務
sudo systemctl enable rc-local
7、啟動服務並檢查狀態
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
8、重啟並檢查test.log文件
cat /usr/local/test.log
如果能看到內容，說明設置成功，你就可以通過編輯rc.local文件來設置啟動腳本了開機自動還原
root@Veriton-M4660G:/backup# cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
#echo "看到這行字，說明添加自啟動腳本成功。" > /usr/local/test.log
/backup/a.sh
exit 0
root@Veriton-M4660G:/backup# cat a.sh
#!/bin/sh
TODAY=$(date +"%d-%m-%Y")
strdir="CA53"
echo $TODAY > /backup/log.txt
echo $strdir >> /backup/log.txt

done
exit 0
