@C0n57an71n I am returning user of Ubuntu Touch. When I first used it in 2017 (?), there was no such nice idea like Libertine. So, today was my first try with Libertine. I think Libertine could offer many benefits, so I hope at least to see some workaround suggestions ...

@C0n57an71n Oh, I misread your message. I will have a browse in this channel, but maybe a forum is a better place for such topics. Let's see.

@C0n57an71n My question is not related to Matrix, it is about good old "ad-hoc wifi networks" to be found in the network managers of most Linux distributions.

To clarify my question: Both devices should receive stable (local network) IPs and both IPs should have similar rights. The hotspot schema does not fulfill this, I guess. In general, this approach should allow for 3 or more devices that can open sockets to others in the same local network.

I need to regularly connect two UT devices without using the internet. With other OSes, I just created a new Wifi network on device 1 (once) and connected device 2 to it. I could not find such an option in UT (under "System Settings" | "Wi-Fi").

(Note: A solution with a cable would be interesting, but a wireless solution would be somewhat better.)

@Lakotaubp I only worked with the new version (0.5.3 beta). I opened an issue for this: https://github.com/ubports/ubports-installer/issues/1441

@Lakotaubp Booting to fastboot mode before starting ubports-installer did the trick. Thanks. Maybe a message in the start screen of ubports-installer would help ("If your device already runs some version of UT, please ...").

@Lakotaubp Yes, I see no output from the terminal command fastboot devices.

@Lakotaubp I tried 0.5.3 beta without any change. Probably the reason is simple: fastboot devices won't show the OP3. In syslog, the following appears when I plug in the USB cable:

Should I move this to a new topic?

@Lakotaubp Thanks for your suggestions. I checked again: no other channels available (probably the installed one was an early one). Now I am trying the ubuntu installer 0.5.2-beta. My OP3 is running, developer mode is on, but the installer is only showing Waiting for device.

If I select the model by hand, installation ends with lost connection. I am using the official OP3, red USB cable.

My OP3 runs an edge version from 2020-07-21. I would like to switch to another channel ("dev"), but only "edge" is offered under Updates|Update settings|Channels.
