What the editor wants to share with you this time is what needs to be done after installing Ubuntu 20.04. The article is rich in content, and interested friends can learn about it. I hope you can get something after reading this article.

Ubuntu 20.04 has been released, bringing a lot of new features, but also with a lot of things that you are not used to, so you have to make a series of optimizations after installing the system.

1. Delete libreoffice

Although libreoffice is open source, the execution efficiency of office written by Java is really unflattering. After installing the system, delete it decisively.

Sudo apt-get remove libreoffice-common

two。 Delete the self-contained software that you basically don't use (it's not too late to install it when you use 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-installsudo apt-get remove onboard deja-dup

So the system is basically clean.

3. Install Vim

Unexpectedly, there is no integrated Vim artifact 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 files.

And then

Sudo apt-get install libappindicator1 libindicator7sudo dpkg-I google-chrome-stable_current_amd64.deb sudo apt-get-f install

This allows apt to install and update chrome browsers later.

6. Install Sogou Input

Vim / etc/apt/sources.list.d/ubuntukylin.list file, apt source for adding ubuntukylin

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

And then

Sudo apt-get updatesudo apt-get install sogoupinyin

This way you can install and update Sogou Input on apt.

7. Install WPS Office

At present, MS does not have a Linux version of Office, so we can only make do with 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

Because the system comes with OpenJDK, there will be residue after uninstalling OpenJDK, which causes the system to run

Java-version

The first line is not the java version number, but the Picked up JAVA_TOOL_OPTIONS:-javaagent:/usr/share/java/jayatanaag.jar prompt, causing many scripts that detect java version numbers to run errors, so you need to remove the residue manually.

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

Delete the / usr/share/upstart/sessions/jayatana.conf file, restart and then run java-version and there will be no more Picked up JAVA_TOOL_OPTIONS:-javaagent:/usr/share/java/jayatanaag.jar prompts.

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 the Classic menu indicator

Sudo add-apt-repository ppa:diesch/testingsudo apt-get updatesudo apt-get install classicmenu-indicator

11. Install the system indicator SysPeek

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

twelve。 Customize the DNS Server IP address of the DHCP network

Sudo vim / etc/dhcp/dhclient.conf file, on line 21 # prepend domain-name-servers 127.0.0.1; add the following two lines of DNS using aliyun and 114

Prepend domain-name-servers 114.114.114.114 prepend domain-name-servers 223.5.5.5

This allows you to give priority to aliyun's dns and secondary to 114s DNS.

13. Install git and vpnc

Git and vpn everyone knows, a good tool for programmers.

Sudo apt-get install vpnc git

14. Install axel

Axel is a multithreaded download tool for the Linux command line interface. The 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 multithreaded downloads instead of wget.

15. Install openssh-server

Sudo apt-get install openssh-server

After installation, you can log in remotely with ssh tools under Win, of course, there is also a security hazard, if you do not want to log on to the local machine remotely, you do not have to install openssh-server.

16. Install CMake and Qt Creator

CMake and Qt Creator are artifacts 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 an artifact for viewing logs in the terminal interface.

Sudo apt-get install lnav

After being installed, the log can be displayed in lnav color in the terminal.

18. Install unrar

The system does not have the function of decompressing rar files by default, and install the unrar program manually

Sudo apt-get install unrar

Once installed, you can extract the rar file with the command.

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

After reading this article about what you need to do after installing Ubuntu 20.04, unrar x test.rar can share it with more people if you think it is well written.
