Streisand: Installation failure at ocserv: Dependency failed for OpenConnect

After I never encountered installation issues for like two years, the installation stops while trying to install ocserv. I use an Ubuntu 16.04 VPS:

TLDR;
you probably have another service (like nginx) listening on port 443, stop it and re-run the installation.

I had the same problem, after checking journalctl using sudo journalctl -xe I found out that ocserv was not able to start because its port was used (port 443).

Then I remembered that I have an nginx on the machine, and it's using port 443 for HTTPS. I turned it off using sudo systemctl stop nginx and re-ran the installation.

After many attempts to make it work a reinstall helped :)

Heh. Reopen if it happens again? I'm a little worried about systemd hating us.

but i get these outputs:
