Hey,

does this work with newer versions of ubuntu which changed to netplan? Is there anything special to consider?

Thanks and regards!

I haven't tried it, and haven't used netplan, but, according to this, it should work.

NetworkManager needs to be in control of networking.

I tried a bit around with the latest ubuntu 22.04, but it does not work. I activated NetworkManager and disabled networked. But anyway netplan is the recommended way to go for ubuntu 20.04+. So is there any chance there will be an update to netplan networked?

Thanks!

I will not address this anytime soon.

Though, as always, I promise to promptly review patches.

I was able to get it working on 22.04 except for ssid scanning

## AS ROOT
systemctl disable systemd-networkd.service
systemctl mask systemd-networkd.service
systemctl stop systemd-networkd.service
apt-get install network-manager -y
apt install vim -y
netplan generate
systemctl unmask NetworkManager
systemctl enable NetworkManager
systemctl start NetworkManager
apt-get install --reinstall resolvconf -y
systemctl stop systemd-resolved
systemctl mask systemd-resolved
sytemctl disable systemd-resolved
vim /etc/resolv.conf and set nameserver to 1.1.1.1
resolvconf -u # this disables updating and fixes resetting problem
apt install comitup -y
## There is a bad bug in python-networkmanager that causes comitup to crash, once this is merged in and ubuntu picks it up this may no longer be needed but do it for now https://github.com/seveas/python-networkmanager/issues/93
wget https://davesteele.github.io/comitup/deb/python3-networkmanager_2.2-1dss01_all.deb
dpkg -i python3-networkmanager_2.2-1dss01_all.deb
## Some of these services may not exist but it doesnt hurt to make sure they never conflict with comitup
rm /etc/network/interfaces
systemctl mask dhcpd.service
systemctl restart comitup

I keep seeing

In the service logs, manually entering ssid works. Any idea why this is happening?

I have confirmed my device is able to scan for ssid by running iw dev <device> scan .

I can see networkmanager scanning SSIDs when I connect to comitup hotspot

I would expect a Traceback in one of the logs from that error. That output would be useful.

Or, stop the service and run "comitup" as root from the command line, to see error infomation on the console.

It may help to change INFO to DEBUG in /usr/share/comitup/comitup/comitup.py.

The output you posted has a reference to seveas/python-networkmanager#93. That issue can be a problem for comitup (the app crashes if one of the connections doesn't have DNS defined). I added a patched (python3-)NetworkManager to the Comitup repository to correct the problem.

Seeing this after enabling debug. Thank you for looking into this. I also am already using your network manager patched package as well.

I added some manual print statements, I see SSIDS in the scan returning they just do not get passed to the web interface somehow.

Your logs suggest you may be running a pretty old version of Comitup - the one included in Ubuntu 22.04. Current is 1.37-1. Consider the repo.

Note that I incorrectly referred to python3-networkmanager as NetworkManager in my comment above.

Try "sudo python3 iwscan.py wlan0" (^d to terminate the stdin read).

I am not sure if this is intended behavior

Any idea why the data is dropping when being passed to the web service? Manually entering SSID works on latest version.

Interesting note, I would say bout 1/20 times I run comitup-cli the access point list presents itself, could the service be crashing and restarting somehow causing these inconsistencies?

If the service crashes/restarts, the comitup-cli connection is lost, and has to be restarted.

It's not intended behavior, but I don't know what is going on right now.

@davesteele Any insights on where I should look? Or any ideas etc? I am willing to try to possibly fix this, I just figure anything that pops into your head could potentially save me a lot of time.

If it means anything, the device I am trying to get this to work on is an Intel NUC

@davesteele

Start by finding any tracebacks in e.g. daemon.log, or run in the terminal, with possibly debug-level logs.

Naterd commented Jul 28, 2022

The wifi driver for the Intel NUC does not support scanning for access points while already in AP mode.

Comitup logic is to scan for access points while also being an access point itself so this would not work at all for my wifi driver. https://github.com/davesteele/comitup/blob/main/comitup/statemgr.py#L71

I was able to work around this problem by modifying statemgr to scan for APs at startup and storing that in a global variable before it entered Access point mode, thus populating the SSIDs correctly when loading the web portal.

The drawback to this is it will not continue to scan for new SSIDs, you may need to restart the service to pick up new SSIDS if they were set up after the commitup service had started.

... or add another USB WiFi adapter. Comitup will make use of it to do the scan.

Be sure to set enable_appliance_mode according to your wishes.

Yes unfortunately that was not an option for me

Greetings I tried to get comitup working for the OpenMower project
and finally got it working without stopping/disabling/masking systemd-resolved on ubuntu-20.04.4-preinstalled-server-arm64+raspi

I found a hint at the pi-hole install instructions

After this small hint I got it working like that:

wget https://davesteele.github.io/comitup/latest/davesteele-comitup-apt-source_latest.deb
sudo dpkg -i --force-all davesteele-comitup-apt-source_latest.deb
rm davesteele-comitup-apt-source_latest.deb
sudo apt update
sudo apt install comitup

# we need to disable systemd-resolveds caching DNS stub resolver
# if you want to know why check: https://github.com/pi-hole/docker-pi-hole/#installing-on-ubuntu
sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf
sudo systemctl restart systemd-resolved.service

ping ntp.org
# This will throw an dns error:
#   ping: ntp.org: Temporary failure in name resolution
sudo sh -c 'rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf'
sudo systemctl restart systemd-resolved.service
nslookup ntp.org
# DNS should work now

Now I tried to install it following the github wiki guide and

wget https://davesteele.github.io/comitup/latest/davesteele-comitup-apt-source_latest.deb
sudo dpkg -i --force-all davesteele-comitup-apt-source_latest.deb
rm davesteele-comitup-apt-source_latest.deb
sudo apt update

the apt sources.d listing:

deb [signed-by=/usr/share/keyrings/davesteele-archive-keyring.gpg] http://davesteele.github.io/comitup/repo comitup main

and apt mentions:

N: Skipping acquire of configured file 'main/binary-arm64/Packages' as repository 'http://davesteele.github.io/comitup/repo comitup InRelease' doesn't support architecture 'arm64'

@davesteele do you an idea what is wrong here?

@davesteele

I had not included arm64 in the repository.

Try it again, and tell me how it works.

@davesteele 👍 It works now - Thanks

Did you also read my previous post regarding systemd-resolved?
Would that be a better solution than completely disable resolved?

@davesteele

I haven't looked into that yet.

I added a link in the Installing Wiki page to this method.
