So, i've configured my raspberry pi 4 64bit/4GB RAM by installing Ubuntu Desktop 64bit (Groovy Gorilla)
Setup all my regular tools and when i tried to install Citric Workspace App, it failed.
First if all, Citrix Workspace App is only available for 32bit ARM (armhf) :(
Downloaded the citrix workspace app (Citrix Workspace app for Linux (ARM HF) from here https://www.citrix.com/downloads/workspace-app/linux/workspace-app-for-linux-latest.html
AS i've installed 64bit ubuntu, enabled the 32bit architecture by running as sudo
sudo dpkg --add-architecture armhf
sudo apt update
Now tried installing the workspace app
sudo dpkg -i icaclient_20.10.0.6_armhf.deb (the one i downloaded, replace with appropriate version.)
Got back the error
Errors were encountered while processing:
icaclient:armhf
After searching/reading through forums, found this article. The gist is,
edit the below file
sudo vim /var/lib/dpkg/info/icaclient.postinst
Look for below line in function UpdateMachineHWSuffix
echo $Arch|grep -i "^arm" >/dev/null
and replace with below
echo $Arch|grep -E "^arm|aarch64" >/dev/null
Then just run the below command
sudo dpkg --configure icaclient:armhf
Now, if you see any error with Entrust certificates, as per this article, execute the below
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
Basically we are just asking citrix workspace app to reuse the existing certificates from firefox.
That's all!
