Trouble with installing on ubuntu server 22.04 on Raspberry Pi 3B

[vino-dk]

I've followed the instructions on a clean image of ubuntu server 22.04 for Raspberry Pi 3B and I've narrowed down the problem to nymea-networkmanager failing to start:

I | Application: Using configuration file from: "/etc/nymea/nymea-networkmanager.conf"

Looks like the daemon started, are there more logs? The NymeaService warnings are not a problem, that's an optional feature if running along nymead.

Is your bluetooth setup ok?

Hi, coworker here, working on the same problem. Good to know that the warnings are not the problem. Output from hciconfig -a:

Turns out that running service nymea-networkmanager restart after booting works perfectly, so it seems that the service starts up before bluetooth is ready to use somehow.

Sounds like a race condition or something changed in Jammy we are not aware of yet. Need to check what changed since there are other issues which might be 22.04 related.

[vino-dk]

I agree that it could have something to do with a race condition during boot-up. To mitigate this I added multi-user.target to the requires field in the nymea-networkmanager.service file. It seems that once the system has started the service files for this requirement, the advertisement starts and shows up in the berrylan app.

However this takes a while (~3 min), so I'll try to see if I can apply a different target or just disable some services that we won't use required by multi-user.target.

Actually, the service is wanted by the graphical.target, and is configured to be started After the multi-user.target, since we already had once such a situation, reaching the graphical.target all required services are up and running (network-manager and bluez).

Are there more logs if you do a clean boot? Like warnings or something?

[vino-dk]

On a clean image of ubuntu server 22.04, we did the following steps to make it work. We added nymea to apt sources and fetched the key, then:

Install the apt packages and auxillary packages

sudo apt update
sudo apt install nymea-networkmanager dirmngr

Install Bluetooth

sudo apt install bluetooth pi-bluetooth bluez
Add "btusb" to /etc/modules-load.d/modules.conf

Following this, we edited the nymea-networkmanager.service file so it was wanted by multi-user.target. It reduced the time of device advertisement by 2 min. bringing it down to ~50s from booting up. It works fine but I will get back if we encounter any issues in this regard.
