Howto: Citrix Receiver on Fedora 30

  1. install Workspace App for LInux https://www.citrix.com/downloads/workspace-app/linux/workspace-app-for-linux-latest1.html
  2. install supporting libs dnf install motif motif.i686 libXaw libXaw.i686 libidn1.34
  3. if your ICA server use godaddy certs:
    3.1. copy godaddy’s CA pem https://ssl-ccp.godaddy.com/repository/gdig2.crt.pem into /opt/Citrix/ICAClient/keystore/cacerts
    3.2. cd /opt/Citrix/ICAClient/keystore/cacerts
    3.3. sudo ../../util/ctx_rehash
  4. edit /opt/Citrix/ICAClient/wfica.sh
  5. change $ICAROOT/wfica -file $1 to $ICAROOT/wfica -file "$1" to allow .ica files with spaces in filename
  6. change the runner line again to LD_PRELOAD="/lib64/libcrypto.so.1.0.2o" $ICAROOT/wfica -file "$1" to allow libcrypto to do crypto work
  7. start your ica files using /opt/Citrix/ICAClient/wfica.sh whatever.ica to connect to whatever app on ICA server

Dear Team,

Am using Fedora 30,

Getting error on Citrix reciver, tried all the troubleshooting as above,

PFA,

Please help me to solve this

Thanks @pegleg3941

I fixed my issue,

OS: Fedora 30

  1. Install compat-openssl10
    sudo dnf install compat-openssl10

Once you complete the installation you can see /lib64/libcrypto.so.1.0.2o,

  1. Install the ca-certificates package
    yum install ca-certificates

  2. Enable the dynamic CA configuration feature
    sudo update-ca-trust force-enable

  3. Install Dependencies,
    sudo dnf install motif motif-2.3.4-14.el7_5.x86_64 libXaw libXaw libidn1.34 libjpeg-turbo-utils

  4. Copy the keys

sudo cp -f /etc/pki/ca-trust/extracted/pem/*.pem /opt/Citrix/ICAClient/keystore/cacerts/
sudo cp -f /etc/pki/tls/*.pem /opt/Citrix/ICAClient/keystore/cacerts/
sudo cp -f /opt/Citrix/ICAClient/keystore/cacerts/ca-bundle.trust.p11-kit.crt /opt/Citrix/ICAClient/keystore/cacerts/ca-bundle.trust.crt
  1. Changed /usr/share/applications/wfica.desktop
    Exec=/opt/Citrix/ICAClient/wfica -icaroot /opt/Citrix/ICAClient %f
    to
    Exec=env LD_PRELOAD="/lib64/libcrypto.so.1.0.2o" /opt/Citrix/ICAClient/wfica -icaroot /opt/Citrix/ICAClient %f

Hope this helps someone…

It fixed also my issue on Fedora 31 with his original direction and the rpm package ICAClientWeb-rhel-19.12.0.19-0.x86_64.rpm.
Additional I had to install compat-openssl10 like @jawad846 did for Fedora 30.
I installed also gtkglext-libs and gstreamer-plugins-base to resolve issued reported by hdxcheck.sh in the util directory of the ICA client. For the used virtual desktop I had to copy the pem files (downloaded by the web browser) into the cacerts directory and to run ctx_rehash.

Are you referring to the original poster here or some later version for F31 ?
(i have to fix this for #wife)

Thank you very much, the update to the wfica.desktop file is what I was missing. Citrix workspace launches web based .ica files using wfica.desktop. I can now log in to work with my fedora laptop!!

thanks made it for me as well

thanks @pegleg3941
worked for Citrix workspace 19.12.0.19 on fedora 31.

Finally, after some blood, sweat and tears, it works on my new fedora 31 installation too.

Just two remarks, the motif-2.3.4-14.el7_5.x86_64 should be replaced by motif.i686 , imo :
sudo dnf install motif motif.i686 libXaw libXaw libidn1.34 libjpeg-turbo-utils

And the third cp command didn’t work for me, the file does not exist in this folder. I only see pem files.
sudo cp -f /opt/Citrix/ICAClient/keystore/cacerts/ca-bundle.trust.p11-kit.crt /opt/Citrix/ICAClient/keystore/cacerts/ca-bundle.trust.crt

I followed all instructions on this thread and every time I run a desktop from Citrix Workplace I get a coredump.
Using Fedora 31 & ICAClient-rhel-20.04.0.21-0.x86_64.rpm:

I am facing an issue with citrix client. First my issue surfaced as I was not able to load ica file. After altering the wfica startup script. I am able connect to remote location, it crashes every so often.

I start using following line

Exec=env LD_PRELOAD="/usr/lib64/libcrypto.so.1.0.2o" /opt/Citrix/ICAClient/wfica -icaroot /opt/Citrix/ICAClient %f
