Debian 8, Jessie, Installing Citrix Receiver

Download the Citrix Receiver Client from here:

Now install the client using the commands:

sudo dpkg -i ~/Downloads/icaclient_*.deb ctxusb_*.deb
sudo apt-get -f install # Install missing depends.

Next, configure the client:

sudo /opt/Citrix/ICAClient/util/configmgr &

Without executing this command I would get a brief pop-up and then the Citrix client would simply disappear – no errors were displayed.

Using FireFox? Check here for specific instructions:

SSL configuration for GlobalSign SSL (if you’re using a different CA you can skip this / retrofit to meet your needs).

Download GlobalSign Root CA crt files from:


Convert to PEM format using openSSL:

openssl x509 -inform DER -in Root-R1.crt -out Root-R1.pem -outform PEM
openssl x509 -inform DER -in Root-R2.crt -out Root-R2.pem -outform PEM
openssl x509 -inform DER -in Root-R3.crt -out Root-R3.pem -outform PEM

Copy these to: /opt/Citrix/ICAClient/keystore/cacerts

sudo cp *.pem /opt/Citrix/ICAClient/keystore/cacerts/

Rehash the ICA Client certificates:

sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

Citrix “official” instruction are available here:

If you get SSL Error 61 :: “Contact your help desk with the following information: You have not chosen to trust “GlobalSign RootCA”, the issuer of the server’s security certificate (SSL error 61).”


You haven’t imported / rehashed the necessary SSL certificates for your servers certificate.
