I have no experience with Citrix on linux, perhaps this page - https://help.ubuntu.com/community/CitrixICAClientHowTo will be of help. FYI Linux Lite is based on Ubuntu 14.04.
I realise this is old...
I did/do use Citrix Receiver very occasionally for work.
I have been using it in my XP VM.
I thought I would try this in Linux.
The referenced link worked perfectly(for me), just 1 minor "got-cha"
The very first time you connect via Citrix it will prompt to download/save a file "
Launch.ica"
In Chrome when you download it, you get the download status in the task bar, lower left, with a little arrow.
select the option to "always open files of this type"
From then on, it will always launch straight into Citrix Desktop
