veth down after reboot on bionic beaver (netplan) systemd

First, please forgive my lame markdown skills.

Running Bionic Beaver: host:~# lsb_release -a Distributor ID: Ubuntu Description: Ubuntu 18.04.2 LTS Release: 18.04 Codename: bionic Can’t seem to figure out the best way to make sure my veth devices automatically “link up” after reboot.

My use case for the veth: I use them for attaching local network bridges to containers. I do this because attaching docker macvlan directly to the bridge inhibits communication between the containers and their host.

Now that that is out of the way:
I’ve tried putting: ip link set veth1a up ip link set veth5a up in /etc/rc.local I had to create new and add execute permissions, but did nothing upon reboot.

I have the interfaces listed in netplan, but this only successfully brings up the bridge side of the veth e.g veth1b: network: ethernets: enp131s0f0: dhcp4: false enp131s0f1: dhcp4: false enp6s0: dhcp4: false enp7s0: dhcp4: false veth1a: dhcp4: false veth1b: dhcp4: false veth5a: dhcp4: false veth5b: dhcp4: false bridges: br0: dhcp4: true interfaces: - enp6s0 - enp7s0 - veth1b br5: dhcp4: false interfaces: - vlan5 - veth5b vlans: vlan5: id: 5 link: br0 dhcp4: false version: 2 I also have some systemd configs to create the veths in the first place, but I don’t know how to tell systemd to “admin up” the veth1a and veth5a. This is what I need help with. host:~# cat /etc/systemd/network/25-veth-* [NetDev] Name=veth1a Kind=veth [Peer] Name=veth1b [NetDev] Name=veth5a Kind=veth [Peer] Name=veth5b

Bionic Beaver does not recognize wifi adapter

I have installed Ubuntu 18.04.2 LTS on my HP laptop model 15-da0012dx. Ubuntu is not recognizing the internal wifi adapter. Settings says “No Wi-Fi Adapter Found”.

This thing does have an internal wifi adapter; I formerly used it with the preinstalled OS. HP describes it as “802.11b/g/n (1×1) Wi-Fi┬« and Bluetooth┬« 4.2 combo”. (full mfg specs at https://support.hp.com/gb-en/document/c05997533

I have also tried to find the wifi adapter from the command line (lshw -C network, lspci), but it doesn’t appear.

How can I properly configure a WiFi connection on my Lubuntu 18.04.2 LTS Bionic Beaver live USB?

I’m new to Linux. My laptop is a

HP 250 G6 Notebook PC Processor: Intel Core i3-6006U CPU @ 2.00 GHz RAM: 4 GB x64

I’m willing to install Lubuntu 18.04.2 on it. I already downloaded the ISO for the desktop amd64 version of this distro and burnt it into a live USB using Rufus. However, when I smoothly run the live session from the USB, the OS seems to work well. But I have a small problem with my internet connection. It only offers me a wired internet connection but at the moment, my only way of connecting to the internet is through WiFi. So I need to manually configure these WiFi settings… I input the SSID, the password and type of security, the channel and the band… But I have no idea what I should pick on “Mode”, “BSSID”, “MUT” or “Cloned MAC address”… Or if I should enter the gateway or the DNS that the Windows connection has… or just let it automatically configure it all? Could you help me out here? I’ve been in love with Linux for a few years now but I haven’t had my hands dirty on it, because I used to get frustrated for not being able to do simple things as connecting to the internet automatically as in Windows… But I’d really like to start improving my Linux skills. Thank you very much.
