Trying to install openvpn and easy-rsa

I have a problem when I try to install openvpn inside a container.
I’m running an Ubuntu14 container inside an Ubuntu16 host.
When I try to install easy-rsa inside the container I’m encountering this error.

`apt-get install openvpn easy-rsa

pcscd is unlikely to make sense in a container, you may want to remove that

but pcscd is a dependency for easy-rsa.
Is there any way to install easy-rsa from ubuntu packages without this dependency?

It’s not a dependency, it’s a recommends, so it can be removed without easy-rsa going away.

Thanks for the quick help.

Steps to install openvpn on my container.

apt-get install easy-rsa

Result: Errors were encountered while processing:
pcscd, opensc

apt-get remove --purge opensc pcscd

apt-get autoremove

The following packages will be REMOVED:

apt-get install openvpn

After that everting works fine. Thanks!

you could also pass --no-install-recommends to your initial apt-get, that should prevent those pacakges from getting installed in the first place.
