Description:
After upgrading from OpenVPN 2.3.8 from 2.3.5 attempts to start an OpenVPN connection via systemd do not include a prompt for certificate private key password. Instead, only the username and password prompts appear. Executing OpenVPN outside of systemd via command line works correctly and prompts for username, password, and certificate private key password are provided.

There are no errors that I can see.

Removing --daemon from the unit file results in the prompt for the private key password appearing, but this is not ideal.
Adding --askpass to the unit file does not appear to have any effect.

Additional info:
openvpn 2.3.8-2

Steps to reproduce:
Launch openvpn via systemd with a private key requiring a password.

In a Qt environment? May have to do with pinentry-qt4 no longer existing.

Previously the password prompt would show up in the console, not a pop-up. GPG password prompt is a pinentry and works fine.
If there's something specific you need me to provide just let me know.

Test with 2.3.9, there is new fix about systemd askpass.

Yes, report this issue upstream. There is at least 2 bug reports about this kind of trouble closed as fixed in last version.

As advised in OpenVPN ticket 641 (https://community.openvpn.net/openvpn/ticket/641#no1), adding --askpass to the unit file after upgrading to 2.3.9 is required in order to receive a prompt for the certificate private key password.
Modifying /lib/systemd/system/openvpn@.service as follows resolved the issue for me.

[Unit]
Description=OpenVPN connection to %i

[Service]
Type=forking
ExecStart=/usr/bin/openvpn --cd /etc/openvpn --config /etc/openvpn/%i.conf --askpass --daemon openvpn@%i --writepid /run/openvpn@%i.pid
PIDFile=/run/openvpn@%i.pid

[Install]
WantedBy=multi-user.target

No need to change the unit. Put askpass in your ovpn config.
