Dear Maintainer, Amazon workspaceclient was working with libicu67. However it is broken with upgrade to libicu71.1. Please see the error from running the application : hizibiz@hizlap2:~$ /opt/workspacesclient/workspacesclient -l3 Process terminated. Couldn't find a valid ICU package installed on the system.
