I'm trying to configure OpenVPN on my Debian 7 VPN but I'm getting the following error ERROR: could not insert 'tun': Unknown symbol in module, or unknown parameter (see dmesg)

I tried the suggestions in the comments here https://www.digitalocean.com/community/questions/modprobe-tun-error-could-not-insert-tun-unknown-symbol-in-module

When I do apt-get install linux-image-$(uname -r) it says it's already installed, also tried rebooting.

Someone also suggested upgrading to the latest kernel, I'm now on Debian 7.0 x64 vmlinuz-3.2.0-4-amd64 (3.2.63-2+deb7u1) but the problem persists.

Suggestions? Thanks.

  • Silly question, you have rebooted since you last updated your kernel right? Is that your post in the thread you linked to? Do you see the same output in dmesg? – Zoredache Nov 18 '14 at 20:01

    @Zoredache Yeah I did, thought it would do it automatically but apparently not so I did it manually. My dmesg is filled with these : `[ 3300.981814] tun: Unknown symbol ipv6_proxy_select_ident (err 0)` – Roemer Nov 18 '14 at 20:13
  • @Zoredache I don't have a ipv6 address by the way. My VPS is hosted at DigitalOcean with an ipv4 address – Roemer Nov 18 '14 at 20:17
  • Have you seen this? https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767836 It appears like you must take some steps on Digital Oceans when updating a kernel. – Zoredache Nov 18 '14 at 20:18
  • @Zoredache Stumbled upon it. I changed my kernel in the DO control panel but I'll try a different version. – Roemer Nov 18 '14 at 20:22
  • @Zoredache Okay so I tried Debian 7.0 x64 vmlinuz-3.2.0-4-amd64 (3.2.60-1+deb7u3) which seems to work for most people with similar problems but I'm getting the same errors. – Roemer Nov 18 '14 at 20:35
