Discord has been one of the fastest growing communication platforms on the planet right now but unfortunately they do not publish an official client for Chrome OS so Chrome OS users are stuck using the web application. While the web application is pretty good, some would wish to have access to the desktop application. Fortunately it is pretty easy to install, here are the steps.
Note : Voice/Audio Support in Crostini is not yet working so this is currently limited to chat only at this time. This is a limitation of Crostini and not the discord application itself.
Aside from performing an initial install, these instructions can also be used to upgrade existing installs of the Discord client.
Go ahead and fire up your favorite terminal application and run the following:
sudo apt install libappindicator1 libatomic1 libc++1 libdbusmenu-glib4 libdbusmenu-gtk4 libindicator7 wget wget -O discord.deb https://discordapp.com/api/download?platform=linux&format=deb sudo dpkg -i discord.deb rm discord.deb
Once the installation is complete, you can launch the Discord application from your Chrome OS Application Launcher and either sign0in with an existing account or create a new account.
I have created a test Discord Room for this website that you can join via https://discord.gg/79Pwk2d if you would like to test it out. Feel free to ask any questions in there and I will try to respond.
