Installation instructions for different flavours of Linux.

Debian/Ubuntu

# 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 repositorysudoadd-apt-repository'deb https://typora.io/linux ./'sudoapt-get update# install typorasudoapt-getinstalltypora

Alternative forapt-key

When you try to add an APT repository key usingapt-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 the following:

1. Download the key and save it locally somewhere.

   curl https://typora.io/linux/public-key.asc | gpg--dearmor> /usr/share/keyrings/typora.gpg

2. Create the repo filetypora.list in/etc/apt/sources.list.d.

   sudovim /etc/apt/sources.list.d/typora.list

3. Paste the repo definition into this file:

   deb[arch=amd64 signed-by=/usr/share/keyrings/typora.gpg] https://typora.io/linux ./

4. Now you can install Typora:

   sudoapt-get updatesudoapt-getinstalltypora

Upgrade Typora

After installing Typora, thetypora package will be managed byapt-get, so when your system updates installed packages, or you executeapt-get upgrade, Typora will be updated to the latest version.

Troubleshooting

Common Solutions for Typora not opening

Make sure all the necessary dependencies are installed. You can runldd typora | grep not on a Linux machine to check which dependencies are missing.

Error on Debian Stretch

For the following error:

[8898:0620/213856.172363:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /usr/share/typora/chrome-sandbox is owned by root and has mode 4755.

Trychmod 4755 /usr/share/typora/chrome-sandbox

See discussion in https://github.com/electron/electron/issues/17972

Cannot open Typora binary “there is no application installed for shared library”

When double clicking on Typora’s binary file, Nautilus (file manager) doesn’t run it as it can’t detect it as an executable file.

This is caused by a Nautilus bug, see discussions in https://github.com/electron/electron/issues/15406. You can either: install Typora viadeb orapt-get, or run Typora from the terminal (./Typora).

Started Typora and gotversion GLIBCXX_3.4.21 not defined in file libstdc++.so.6 error

When you start Typora on Ubuntu 14.x, if the following error happens:

/usr/share/typora/Typora: relocation error: /usr/share/typora/resources/app/node_modules/spellchecker/build/Release/spellchecker.node: symbol _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE10_M_replaceEmmPKcm, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

Then download the Debian version of package libstdc++6 for Xenial at the following link http://packages.ubuntu.com/xenial/libstdc++6 and install it usingdpkg -I (Reference: https://askubuntu.com/questions/777803/apt-relocation-error-version-glibcxx-3-4-21-not-defined-in-file-libstdc-so-6).

[Ubuntu 14.04 ] typora: /lib/x86_64-linux-gnu/libdbus-1.so.3: no version information available (required by Typora)

Seeelectron/electron#16364 (comment)

If you receive the following error when launching Typora:

[7465:7499:0911/174740.042852:FATAL:nss_util.cc(632)] NSS_VersionCheck("3.26") failed. NSS >= 3.26 is required. Please upgrade to the latest NSS, and if you still get this error, contact your distribution maintainer.Aborted

then:

1. Ensurexenial-security updates are included inSoftware & Updates.
2. runsudo apt-get update && sudo apt-get install libnss3

Shortcut for Heading 5 is not working

Please check if you use fcitx (e.g. for typing Chinese)?Ctrl +5 is the global shortcut key for fcitx to reload its config. Deleting that global shortcut should makeCtrl +5 work in Typora. (Thanks to https://github.com/typora/typora-issues/issues/867#issuecomment-647082881).
