Install Typora on Linux

# or use  
# wget -qO - https://typora.io/linux/public-key.asc | sudo apt-key add -
wget -qO - https://typoraio.cn/linux/public-key.asc | sudo tee /etc/apt/trusted.gpg.d/typora.asc
# add Typora's repository
sudo add-apt-repository 'deb https://typora.io/linux ./'
sudo apt-get update
# install typora
sudo apt-get install typora

When you try to add an APT repository key using apt-key (first line in previous command line) on Debian, Ubuntu and Linux distributions based on these, you’ll see the following message: “Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8))”.
The easiest way would be just to ignore it.
But if you’re not OK with the warning, you can do followings:

当您尝试在基于这些的 Debian、Ubuntu 和 Linux 发行版上使用 apt-key（上一个命令行中的第一行）添加 APT 存储库密钥时，您将看到以下消息：“警告：不推荐使用 apt-key。 改为在trusted.gpg.d 中管理密钥环文件（参见apt-key(8)）”。
最简单的方法就是忽略它。
但是，如果您对警告不满意，您可以执行以下操作：

#Download the key and save it locally somewhere.
curl https://typora.io/linux/public-key.asc | gpg --dearmor > /usr/share/keyrings/typora.gpg
#Create repo file typora.list in /etc/apt/sources.list.d.
sudo vim /etc/apt/sources.list.d/typora.list
#Paste repo definition into this file:
deb [arch=amd64 signed-by=/usr/share/keyrings/typora.gpg] https://typora.io/linux ./
#Now you can install Typora:
sudo apt-get update
sudo apt-get install typora

After installing Typora, the typora package will be managed by apt-get, so when your system updates installed packages, or you execute apt-get upgrade, Typora will be updated to latest version.

安装 Typora 后，typora 包将由 apt-get 管理，因此当您的系统更新已安装的包时，或者您执行 apt-get upgrade 时，Typora 将更新到最新版本。

# upgrade all packages include Typora
sudo apt-get upgrade

# or use
# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BA300B7755AFCFAE
wget -qO - https://typora.io/linux/public-key.asc | sudo apt-key add -
# add Typora's repository
echo -e "\ndeb https://typora.io/linux ./" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
# install typora
sudo apt-get install typora

You can also manually download and install the deb package file, following those steps:
    Find download link from https://typora.io/releases/all and download the Linux version.
    Double click the deb file to start installing on Ubuntu / Debian.

    Download the binary package Typora-linux-x64.tar.gz.
    Try to install apt-get on your distribution, and then install typora.
