Is Ubuntu Touch OTA-2 Focal incompatible with the Fairphone 2?

Opolork

Am I correct to I presume my 16.04 version of UT is supported until Apr-2026? By then my FP2 will be about obsolete anyway and I'll likely need a newer smartphone.

@Opolork no, 16.04 has already gone out of support. The ESR offering of Canonical sadly did not cover the ARM architecture for 16.04. It does for 20.04 on the other hand.

Damn.

So effectively, I'm using an unsecure OS on my FP2?

No, you are using an unsupported OS. That does not mean it is insecure. It does mean it will not get any more security updates.
But not all vulnerabilities are equally exploitable. Also, UT's read-only file system and confined application runtime environment go a long way into protecting you additionally. Add to that fact that there are no services running on the device out-of-the box that can be connected to remotely (if you are concerned with security, you should disable ssh on your device, even if on a supported OS), then I would say, realistically, you are probably as safe as you would be on 20.04.

The main reason to stop using 16.04 would be lack of support for newer apps. But we haven't quite gotten there as yet.

disable ssh on your device

Thanks for the advice/info.

How would I disable SSH?

@Opolork You can use UT TT : System / SSH parameters.
It seems for me SSH is reactivated at every start of my Volla. To be checked.

That depends. On most devices, if not all, it should be disabled by default. Certain devices have it enabled when you enable Developer Mode in the settings. So disabling developer mode should see ssh disabled on the next reboot.

One way to check if ssh is enabled on your device is to open the terminal app and type:

ssh localhost

If you get a result saying ssh: connect to host localhost port 22: Connection refused, then the service is disabled.

That's a handy tip.

y'all need focal for FP2?

there

Pardon my intrusion. Just a few questions. Is the port you are showing/using/building usable? Can you describe what works and what not? Is there a way I (or anyone else with FP2) can test the product of your effort?

Thanks.
