I am new to KaOS and I need to install and configure Citrix ICA Client for work. Does anyone use this or know how I can install it?
See https://kaosx.us/#repo for limited repos.
See https://kaosx.us/docs/package to add packages you miss yourself.
If you need a lib32 application, then no go in KaOS:
Closed source software is installed as you know in one way, go to website download, uncompress, run
https://www.citrix.com/downloads/citrix-receiver/linux/receiver-for-linux-latest.html click on tarball packages and download Receiver for Linux (x86_64) then uncompress and run it.
Use firefox , it has builtin citrix receiver.
