To get any software updates for your current system, run

apt-get update && apt-get -y dist-upgrade

How do I check the installed version of OpenVPN server?

There are a number of ways. An easy way is to use apt-cache policy, like this

Code: Select all

pi@raspi6 ~ $ apt-cache policy openvpn
openvpn:
  Installed: 2.3.4-5+deb8u1
  Candidate: 2.3.4-5+deb8u1
  Version table:
 *** 2.3.4-5+deb8u1 0
        500 http://mirrordirector.raspbian.org/raspbian/ jessie/main armhf Packages
        100 /var/lib/dpkg/status

That shows that I have version 2.3.4-5 with Debian security fixes update 1 installed.

rpdom,
Thank you very much as this answers my questions but...

The reason I asked about how to update pi and software like openvpn is two reasons.
One I have been running the commands as you suggested already and the issue is I can run them and run them again immediately and it says there are all these updates to run.
Two using your command I'm running openvpn Installed: 2.3.4-5+deb8u2 but the latest is 2.4.3 or 2.3.17. So I'm guessing this is because of where I'm getting the packages from do not hold the latest versions. I wanted to update because of the security issues just fixed in OpenVPN a few days ago.

Third time in 24 hours I guess was the charm on updating it is no longer seeing any updates needed. You may ignore that part of my last post.

The fixes for that issue are included in version 2.3.4-5+deb8u2. Looking at the latest entry in the Debian changelog /usr/share/doc/openvpn/changelog.Debian.gz:

Code: Select all

Debian sticks to older version of software because they are proved to be stable and suddenly updating can break things when options change. However, when any security related changes are made they also apply them to the old versions and add a "+debXuY" on the end of the version. X=8 for Debian/Raspbian 8 Jessie, and Y starts at 1 and increments with every fix added.

Thanks for letting me know that the updated version has been released. I've just upgraded mine
