Netplan issue on Ubuntu 20.04 LTS (focal)

[rlesac]

Fresh install just edited /etc/netplan/01-netcfg.yaml to change to my details. Any idea?

@bpi-m2z:~$ sudo netplan apply

A dependency job for netplan-wpa-wlan0.service failed. See 'journalctl -xe' for details.

Did you try this one?: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v3.10

How did you change the 01-netcfg.yaml? Don't use windows program for that.

[rlesac]

I used the v3.10 release. Used vim for editing, just changed the network details to mine and that is it.

[avafinger]

Please, check if vim used TABs. Check if you have changed the indentation.

And try:

sudo netplan generate
sudo netplan apply

[rlesac]

The yaml seems valid. Tested with an online validator. Also here's the output of "netplan --debug generate"

i@bpi-m2z:~$ ls /sys/class/net
eth0  lo

I'm missing wlan here.

Also I found this in dmseg:

@bpi-m2z:~$ dmesg | grep -i -E 'wlan0|iwl|80211'

what's the output of:

Maybe there is a new hw release with A2 chip?

[rlesac]

Maybe there is a new hw release with A2 chip?

How do I check? This is my output:

bpi-m2z:~$ dmesg|grep 'brc\|wl\|802'

[avafinger]

Try to find any version printed on the silkscreen

[avafinger]

Also, check what is printed on the wifi chip.

[rlesac]

Seems normal to me.

Wlan was working with your earlier build, but it was not reliable.

[avafinger]

Board version 1.0 is the same as mine. Your Wifi chip version is newer. Can you try with another SD card?
