I'm having issues with getting VLAN configured correctly.
I have followed everything here
https://wiki.ubuntu.com/vlan
but the only way I could get it to work was to go into my interfaces file and add it as
auto vlan5
iface vlan5 inet static
address 192.168.5.3
netmask 255.255.255.0
vlan_raw_device ens3
I can then restart the networking interface and it works, but once I reboot the machine, it takes awhile to reboot and then doesn't have the vlan anymore.
When checking the networking status, I see;
● networking.service - Raise network interfaces

Has anyone else experienced this error, or know how to fix it?
Thanks,
PS - I have been searching for a couple hours now on a fix and haven't been able to find anything.
