My university offers a vpn service using the Cisco Secure Client
https://www.cisco.com/c/en/us/support/security/anyconnect-secure-mobility-client/series.html

I installed it recently and could not get it to work on devuan testing.
The installation script silently failed.

I have only just dicovered an installation log file:

# tail cisco-secure-client-linux64-5.1.12.146-core-vpn-webdeploy-k9-16442805112025.log

Error: systemd required.      <=================
rm -rf /tmp/vpn.b3C17n
Done!
Exiting now.

So that seems to be the problem. The university "IT services" was dumbed
down some years ago, and now seems to be mainly an MS slave, although
they do offer some linux support. I doubt that I will find anyone who
will even understands the significance of requiring systemd.

I am horrified at the prospect of having to give up devuan. Does anyone
here have any insight here. or even better some sort of workaround?
