Can't install citrix workspace

Good evening,

I’m new to the forum and Nixos in general. So far very impressed with the possibilities. I can figure out many things by reading documentation/googling but one thing I can’t seem to get working is my citrix workspace app that I need to login to my work.

So far I’ve followed this thread:

and this one

It seems I have to manually add the downloaded file to the nixos store so I’ve tried that:
nix-prefetch-url file://./linuxx64-
(I’m in the Downloads directory already but I get this output):
error: unable to download ‘file://./linuxx64-’: URL using bad/illegal format or missing URL (3)

I shouldn’t add a url right? Cause I’ve downloaded the file already.

In my configuration.nix I’ve added the following lines which I don’t know yet if they’re going to work:
pkg citrix-workspace
and I’ve added the following config:
nixpkgs.overlays = [
( self: super:
extraCerts = [ /etc/ssl/certs ];
in {
citrix_workspace = super.citrix_workspace.override {
inherit extraCerts;

This config I’ve got from this thread:

Sorry if I missed something to include or to explain a bit better. I’m an absolute beginner when it comes to Nixos. I hope someone can help me out here. Thanks in advance.


I’ve solved the issue. Tested it in the live environment.

First allow unfree packages (I did it just temporary)

Then download the correct tar file from citrix:
It’s important to get the correct version:
linuxx64- so check for older files.

Then add the package to the nix store (this is where I got stuck, beginners mistake I’m affraid)

nix store add-file /home/nixos/Downloads/linuxx64- --extra-experimental-features nix-command

Then fetch the url:
nix-prefetch-url file://$PWD/linuxx64-

Then install the workspace app (I did it temporary in the nix environment)
nix-env -iA nixos.citrix_workspace

I’ve started up the workspace app and agreed. I’ve also installed Chromium (checked on serveral distros but Firefox doesn’t work so far).
I’ve downloaded the .ica file. I had to choose ‘open with’ Citrix workspace engine via Nautilus.

Then it started up flawlessly.
If someone has any questions please feel free to ask.
