How do I upgrade Discord to v 0.0.12?

If you've installed the snap version before, update it with the command sudo snap refresh discord

Else if you've installed discord from the official website, update it through the following steps.

  1. Go here to download the latest .deb file.
  2. Open terminal and go to the folder where you've download the file.
  3. Install it using sudo apt install ./<package name>

Select download on the deb package. Then, wherever you saved this package, do:

sudo apt install ./discord-0.0.12.deb

Running sudo snap refresh discord works as of today. I hope this answered your question.

The response should be something like:

Johndoe@pc:~$ sudo snap refresh discord
discord 0.0.12 from Snapcrafters refreshed
Johndoe@pc:~$

It may take a bit copying over data.
