Ah! I had the exact same problem. If you boot your system without quiet and splash you can see that it's trying to change the permissions but says unknown group vboxusers. I cannot understand why though.
If you instead of changing that file (or in addition to) add a rules file called 10-local.rules with content as pasted below it works. /etc/udev/rules.d$ cat 10-local.rules KERNEL == "tun", NAME="net/%k", GROUP="uml-net", MODE="0660", OPTIONS+="ignore_remove" /etc/udev/rules.d$ grep tun 20-names.rules KERNEL=="tun", NAME="net/%k" -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
