Yeah Discord has been wacky on Linux lately, they pushed maybe 4 different updates the past week that forced you to update the package immediately.
Pro tip: Sync the package manager database before trying to update. It could tell you there are no updates when it's just pacman being out of date.




There aren't any alternatives that are as good or feature-rich. If you're willing to settle for less there's Revolt that's trying to be a 1-to-1 clone but is still in alpha, then there are apps based on Matrix which somehow makes using a chat app 10x harder.
