I had the same issue. In my installation, the file /etc/udev/rules.d/60-vboxdrv.rules already existed (I'm using VBox 2.02).
I added the line per the above comment: KERNEL=="tun", OWNER="root", GROUP="vboxusers", MODE="0660" rebooted, and the problem went away - permissions are now correct. I didn't need to do manually modprobe the tun module. -- Cannot change /dev/net/tun file permissions with udev https://bugs.launchpad.net/bugs/265138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
