If you cannot build because of a missing tar ball or a failed sha256 checksum validation, then the package is most likely outdated and they have removed the old version already. In this case, please click on “Flag package out-of-date”.

Found a fix for "authentication service could not be contacted"

Edit the config file under /home/username/.ICAClient\WFClient.ini and add a new line SSLCiphers=ALL save file and run "killall AuthManagerDaemon ServiceRecord selfservice storebrowse"

Relaunch Citrix and you should be fine

@daniell: Thanks for the details. Without setting that config I had no audio support at all, and with it the playback works again (as it did in previous versions). So it may very well be legacy and incomplete but for my use case (playback only from Windows session, not tested any recording/microphone usage) it is a clear improvement over no audio at all.

@robertlturner, @alexdw, that "solution" does nothing but falls back to a legacy and broken alternative re. audio. With that no HDX support for e.g. Skype and no microphone support either. Citrix have just broken pulseaudio since 20.10, and there's no fix for it currently.

@robertlturner: Thank you for the link on disabling the 'enhanced' audio by adding "VdcamVersion4Support=False" under "[ClientAudio]" in the main "module.ini" config (under "/opt/Citrix/ICAClient/config"). This fixed the audio for me using icaclient 20.12-2, which was previously working but then broken in recent versions.

These lines can be removed from the PKGBUILD, as npica.so is no longer included:

# Copy Firefox plugin into plugin directory
mkdir -p "${pkgdir}/usr/lib/mozilla/plugins"
ln -s "$ICAROOT/npica.so" "${pkgdir}"/usr/lib/mozilla/plugins/npica.so

20.12-[12] completely breaks pulseaudio audio for me:

Had to downgrade to 20.10-3.

The sha256sum in the PKGBUILD for x86_64 needs to be changed to: ca88a1abc93970a0141adcd5613d95116ffbbfd0573e744e5b3846a35778a906

That fixes the validity check error. This is the SHA256 sum from the corresponding file downloaded from Citrix: https://www.citrix.com/downloads/workspace-app/linux/workspace-app-for-linux-latest.html

==> Validating source files with md5sums... configmgr.desktop ... Passed conncenter.desktop ... Passed selfservice.desktop ... Passed wfica.desktop ... Passed wfica.sh ... Passed wfica_assoc.sh ... Passed ==> Validating source_x86_64 files with sha256sums... icaclient-x64-20.12.tar.gz ... FAILED ==> ERROR: One or more files did not pass the validity check! error downloading sources: icaclient

The version of the package is not properly dispatched to the wfica client.

In the DEB package provided by Citrix, the post installation script creates the file pkginf/Ver.core.linuxx64 (or any other supported Architecture) which is used by the wfica client to know which version is currently installed.

Some servers check that version to block outdated clients.

Edit: I'll send a patch.

The latest PKGBUILD creates a symlink in /usr/lib/gstreamer-1.0:

mkdir -p "${pkgdir}/usr/lib/gstreamer-1.0"

ln -s "$ICAROOT/util/libgstflatstm1.0.so" "${pkgdir}/usr/lib/gstreamer-1.0/libgstflatstm.so"

I don't think it's necessary to create that link outside $ICAROOT/util. I just replaced it with the following link and it still works:

ln -s "$ICAROOT/util/libgstflatstm1.0.so" "$ICAROOT/util/libgstflatstm.so"
