How To Fix Citrix Receiver Error 1000119 on Ubuntu Xenial

In this comprehensive guide, we will walk you through the steps to fix the Citrix Receiver Error 1000119 on Ubuntu Xenial. This error typically occurs when trying to run Citrix Receiver and the message “Cannot connect to ‘0.0.0.2 – Remote Desktop Connection’, Unknown error 1000119” pops up.

Solution 1: Remove cacerts and link to /etc/ssl/certs

The first solution involves removing cacerts and linking it to /etc/ssl/certs. Here’s how to do it:

1. Open the terminal and navigate to /opt/Citrix/ICAClient/keystore/ with the command cd /opt/Citrix/ICAClient/keystore/.
2. Run the following commands:

sudo rm -rf cacerts
sudo ln -s /etc/ssl/certs cacerts

The rm -rf command removes the cacerts directory and all its contents. The ln -s command creates a symbolic link between the /etc/ssl/certs directory and cacerts.

Solution 2: Link System Certificates to ICA’s Certificates

Another solution is to link the system certificates to ICA’s certificates. To do this:

1. Open the terminal and run the following command:

sudo ln -s /etc/ssl/certs/* /opt/Citrix/ICAClient/keystore/cacerts

This command creates symbolic links for all files in /etc/ssl/certs to /opt/Citrix/ICAClient/keystore/cacerts. Ignore any warnings about duplicates.

Solution 3: Downgrade to Citrix Receiver 13.2

If the above solutions don’t work, consider downgrading to Citrix Receiver 13.2. You can download the 13.2 x64 version of Citrix Receiver from the official website. Follow the standard procedures for linking certificates as mentioned in the Ubuntu community guide.

Solution 4: Install the Root Certificate

Another alternative is to install the root certificate. Here’s how:

1. Download the root certificate (e.g., Verisign) from the provided link.
2. Copy the downloaded certificate file (e.g., verisign-universal-root-certification-authority-en.pem) to /opt/Citrix/ICAClient/keystore/cacerts.

Solution 5: Check DNS Settings

Incorrect DNS settings can also cause this error. Open the network manager and set the DNS to 8.8.8.8,4.4.4.4.

Solution 6: Download Additional Certificates

If the error persists, you may need to download additional certificates. Open the terminal and run the following commands:

cd /opt/Citrix/ICAClient/keystore/cacerts/
wget https://dl.cacerts.digicert.com/DigiCertHighAssuranceEVRootCA.crt
curl https://support.comodo.com/index.php?/Knowledgebase/Article/GetAttachment/969/821026 > comodorsacertificationauthority.crt
exit

The wget and curl commands download the required certificates and save them to the specified directory.

Solution 7: Install Chrome Citrix Workspace Plugin

Lastly, consider installing the Citrix Workspace plugin for Chrome from the Chrome Web Store. Use the URL of your organization’s “Citrix storefront” when prompted.
