I am able to install and use snx (800008061) in ubuntu:cosmic and bionic.
Install dependencies:
- libpam0g:i386
- libx11-6:i386
- libstdc++6:i386
- libstdc++5:i386
Problem with systemd-resolved can be solved by unlinking /etc/resolv.conf (possible rm -r /etc/resolv.conf && echo "nameserver 127.0.0.53" > /etc/resolv.conf ) and installing libnss-resolve:i386 and libnss-resolve, which will provide fallback resolving in case of missing resolv.conf, which is edited directly by snx.
