I'm trying o install the Appgate VPN client on the latest version of Kali. I downloaded the Ubuntu .deb file from from https://www.appgate.com/support/software-defined-perimeter-support/client. When I attempt to install the file I get a dependency error. It appears that Appgate needs a version of libicu that is lower than the currently installed version. Below is the error message.
$ sudo dpkg -i appgate-sdp_6.0.2_amd64.deb

The installed version of the library is libicu71, as shown below.
$ dpkg -l | grep -i libicu
ii libicu-dev:amd64 71.1-3 amd64 Development files for International Components for Unicode
ii libicu71:amd64 71.1-3 amd64 International Components for Unicode
How can I install a previous version of the library? According to the Kali package tracker, http://pkg.kali.org/pkg/icu, previous versions should be available. I just don't know how install the version I want using apt-get.
$ sudo apt-get install libicu70
