Discord wants latest version
Discord refuses to start because they have released an update and only the latest version can connect to their service.
Most of the time this is a temporary problem, and you can just wait for the version to be bumped in nixpkgs and update then. For the impatient the workaround is something like this:
nixpkgs.overlays = [(self: super: { discord = super.discord.overrideAttrs (_: { src = builtins.fetchTarball <link-to-tarball>; });})];
An overlay to build discord manually from the URL to the latest tarball on [1], see [2]
If it was fixed in master, the other alternatives are:
nix-env -f https://github.com/NixOS/nixpkgs/archive/release-20.09.tar.gz -iA discord
or with nix-shell:
NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/release-20.09.tar.gz nix-shell -p discord --run Discord
Opening Links with Firefox
If you use Discord and it silently fails to open links in Firefox, you possibly have encountered issue #78961. This is caused by a version mismatch between the NSS libraries used by Discord and Firefox. Luckily, a relatively easy workaround is available:
First, find out which NSS version Firefox is currently using with
$ nix path-info $(which firefox) -r | grep nss-
This should print a few store paths, focus on their ends, which should look like nss-x.xx. We're interested in the one with the newest version. Next, create a new file called discord_patched.nix and paste the following code into it:
with import <nixpkgs> {};
pkgs.discord.override {
nss = pkgs.nss_3_49_2;
}
Now replace nss_3_49_2 with the previously looked up version's "attribute name", which you can look up here. Finally, build and install this patched package with
$ export NIXPKGS_ALLOW_UNFREE=1; nix-env -i $(nix-build discord_patched.nix) --arg config '{ allowUnfree = true; }'
Log in again and you should be able to open links properly.
