Utility configuration guide after installing the Ubuntu system

1. Modify the software source

The default software source of Ubuntu is overseas, and there will be some problems in speed. We can Software & Updateschoose the domestic image in (software and update).

Generally, we choose Tsinghua source or Alibaba cloud source.

2. Install Chorme browser

Under ubuntu, I am more accustomed to using Firefox and Google Chrome .

Google Chrome directly downloads the deb installation package from the official website and installs it.

For the Firefox browser, after we install the system, the system will have its own firefox browser, but it is an international version and cannot log in to the domestic Firefox account. Therefore, you need to download the domestic version of Firefox and uninstall the international version of Firefox.

Uninstall method:

1. View related content of Firefox browser

   dpkg --get-selections |grep firefox
   

2. Uninstall all files in the above command

   sudo apt-get purge +每一个包名字
   

   For example

    sudo apt-get purge firefox   firefox-globalmenu  firefox-gnome-support   firefox-locale-en   firefox-locale-zh-hans
   

Here is how to download.

• Enter the Chinese version of the official website to download the software
  

  Note: firefox.com.cn is the Chinese version of the official website operated by Beijing Mozilla, a wholly-owned subsidiary of the Mozilla Foundation, and mozilla.org is the international version of the official website operated by the Mozilla Foundation.

• Open a terminal and go to the directory where you downloaded Firefox, such as

  cd ~/Downloads
  

• Extract the contents of the downloaded file:

  tar xjf firefox-*.tar.bz2
  

• Move the unpacked Firefox directory to /opt:

  sudo mv firefox /opt
  

• (This step is optional) Create a symlink pointing to the Firefox executable:

  sudo ln -s /opt/firefox/firefox /usr/local/bin/firefox
  

• Download a desktop file:

  sudo wget https://raw.githubusercontent.com/mozilla/sumo-kb/main/install-firefox-linux/firefox.desktop -P /usr/local/share/applications
  

  If wget is not installed, the file can be created manually:

  #移动到/usr/share/applications目录
  cd /usr/share/applications
  #修改firefox.desktop文件
  sudo gedit firefox.desktop
  

  Paste the following into the opened file:

  [Desktop Entry]
  Name=firefox
  Name[zh_CN]=火狐浏览器
  Comment=火狐浏览器
  Exec=/opt/firefox/firefox
  Icon=/opt/firefox/browser/chrome/icons/default/default128.png
  Terminal=false
  Type=Application
  Categories=Appliction;
  Encoding=UTF-8
  StartupNotify=true
  

• Finally, restart the system to take effect

  sudo reboot
  

2. Chinese input method
