What to do after installing Ubuntu 20.04 (beginner's guide)

Ubuntu 20.04 has been released, bringing many new features, but also many things that you are not used to, so a series of optimizations need to be performed after installing the system.

1. Remove LibreOffice

Although libreoffice is open source, the efficiency of office written in Java is really not satisfactory. I deleted it decisively after installing the system.

sudo apt-get remove libreoffice-common

2. Delete the built-in software that you don’t use (you can always install it later when you need it)

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install

sudo apt-get remove onboard deja-dup

This way the system is basically clean.

3. Install Vim

There is no Vim artifact integrated by default, so it can only be installed manually.

sudo apt-get install vim

4. Set the time to use UTC

sudo vim /etc/default/rcS

Change UTC=no to UTC=yes

5. Install Chrome

Go to https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb to download the latest installation file.

Then

sudo apt-get install libappindicator1 libindicator7
sudo dpkg -i google-chrome-stable_current_amd64.deb 
sudo apt-get -f install

This way you can apt install and update the chrome browser in the future.

6. Install Sogou Input Method

vim /etc/apt/sources.list.d/ubuntukylin.list file, add apt source of ubuntu kylin

deb http://archive.ubuntukylin.com:10006/ubuntukylin trusty main

Then

sudo apt-get update
sudo apt-get install sogoupinyin

This way you can apt install and update Sogou input method.

7. Install WPS Office

Currently, MS has not released a Linux version of Office, so you can only use WPS.

sudo apt-get install wps-office

8. Install Oracle Java

sudo add-apt-repository ppa:webupd8team/java 
sudo apt-get update 
sudo apt-get install oracle-java8-installer 

Since the system comes with OpenJDK, there will be some residue after uninstalling OpenJDK, which will cause the running

java -version

When the first line is not the Java version number, it will be Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar. This will cause many scripts that detect the Java version number to run incorrectly, so you need to manually clear the remaining ones.

sudo rm /usr/share/upstart/sessions/jayatana.conf

Delete the /usr/share/upstart/sessions/jayatana.conf file. After restarting, when you run java -version, there will no longer be a prompt of Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar.

9. Install Sublime Text 3

sudo add-apt-repository ppa:webupd8team/sublime-text-3 
sudo apt-get update 
sudo apt-get install sublime-text

10. Install Classic Menu Indicator

sudo add-apt-repository ppa:diesch/testing
sudo apt-get update
sudo apt-get install classicmenu-indicator

11. Install SysPeek

sudo add-apt-repository ppa:nilarimogard/webupd8 
sudo apt-get update 
sudo apt-get install syspeek

12. Customize the DNS Server IP address of the DHCP network
sudo vim /etc/dhcp/dhclient.conf file, in line 21 #prepend domain-name-servers 127.0.0.1; add the following two lines to use aliyun and 114 DNS

prepend domain-name-servers 114.114.114.114;
prepend domain-name-servers 223.5.5.5;

In this way, aliyun's DNS can be used first, and 114's DNS can be used secondarily.

13. Install git and vpnc

Everyone knows about git and VPN, which are good tools for programmers.

sudo apt-get install vpnc git

14. Install axel

Axel is a multi-threaded download tool for the Linux command line interface. Its advantage over wget is that it can specify multiple threads to download files in the command line terminal at the same time.

sudo apt-get install axel

After installation, you can use multi-threaded downloading instead of wget.

15. Install openssh-server

sudo apt-get install openssh-server

After installation, you can use the ssh tool to log in remotely under Win. Of course, there is also a security risk. If you do not want to log in to the local machine remotely, you can choose not to install openssh-server.

16. Install CMake and Qt Creator

CMake and Qt Creator are great tools for developing C++ programs under Linux. Ubuntu 20.04 has integrated the latest version of Qt Creator.

sudo apt-get install cmake qtcreator

17. Install lnav

The lnav tool is a great tool for viewing logs in the terminal interface

sudo apt-get install lnav

After installation, you can use lnav to display logs in color in the terminal.

18. Install unrar

The system does not have the function of decompressing rar files by default. Manually install the unrar program

sudo apt-get install unrar

After installation, you can use the command to decompress the rar file.

Use the following command to decompress the file to the current directory.

unrar x test.rar
