@Lakotaubp Thanks. I'll try to upgrade before the 23rd of April and have a look then.
I will post here again some instructions to have debugs logs. I will not be available around 23rd of April. Hope it will work that time.
We already had 2 tests failures and 1 success on 20.04. But we need to add more debug logs in case of failure. -
For the next tests, make sure you will be updated to the latest devel 20.04 before .
To make sure all channels are subscribed, toggle on all items in System Settings->Notifications->Emergency BroadcastDepending of the Level of Cell Broadcast Message, the notification can be either a persistent popup with loud vibration in case of real emergency test or a simple notification with usual sound just like normal if the message is considered as a "Test" ( i know Android do it differently for that one, we should change it ).
Notifications can be seen in indicator and messaging app.If nothing received there should be a log that can be caught with :
sudo journalctl | grep CBSPlease report here if any success ( screenshots) or failure ( logs )
I will not be available during the UK test . Finger cross for you ^ ^

@lduboeuf My current plan is to back up my data then do a clean install of 20.04 OTA-1 on my Volla Phone X next Friday or Saturday. I then plan to switch to the dev channel to be ready for the test on Sunday in the UK at 3 pm.
EDIT : I see you have edited your post, thanks for the clarification.
Please ignore the remainder of this paragraph. Will the above mentioned merge be in the dev channel or do I need to do it manualy? If so can you point me at some guidance on this please?After the test I then hope to do a clean install of OTA-1 and hope it is stable enough ro use as a daily driver.... if it is not then I will roll back to 16.04 OTA-25 and restote my data.
-
hope OTA-1 is stable enough ro use as a daily driver.
OTA-1 is the beginning of focal. OTA-2 will have more stability. But Xenial level stability should be for OTA-3 for what i know. In any case, OTA-1 does not have the hotspot operational.
-
@domubpkm It is the hotspot I will miss, but if OTA-2 is not too far away I think I can manage.
As I say I plan to stick with 20.04 if it works for me as a daily driver (note to self: must get a BT keyboard for my fat fingers).
-
@Ian You shouldn't miss Tedit either because no official .click yet
I need Tedit too to go to focal. -

The mentionned Merge request as just landed in devel so nothing need to be done more than switching to devel ;-).
FYI i'm on 20.04 devel since more than a month and daily driving it. -
@lduboeuf My Volla Phone X is running 20.04 dev channel r725 amd I heard nothing.... other than my wife's Android phone.
All the alerts were on in the settings, but both 'Cell Broadcast Enabled' and 'Receive emergeny notifications' were on but greyed out.
I will see what logs I can get.
EDIT: the journalctl returned nothing and I checked through all logs visible in Logviewer and there was nothing either side of 15:00.
I will stay on the dev chanel in case you want me to dig further through the logs. When you say so I will revert to stable.
Further edit: I live near to Newark, which is the back of beyond. Imagine walking from the edge of civilisation towards 'nowhere'. You will walk past Newark
I have just checked my phone status and it claims to be 3g, not 4g so I guess that explains it. I am on the Three network (my wife has recently moved to Virgin who I believe piggy-back the O2 network). -
@Ian Nothing on P3a dev 20.04 also.

I am on the Three network (my wife has recently moved to Virgin who I believe piggy-back the O2 network).Bad luck. I don't think 3G/4G have any impact. Cell Broadcast is something that should work for all connectivities.
Now i don't know what to look at. If journalctl doesn't output anything with "CBS".
Could be lots of causes ( modem, layer in between android and UT, upper layers, ... )But i would be interested to see the logs if possible by dm it to me.
I'm not at home currently -
@Lakotaubp nothing in logs ?
-
@lduboeuf I have run journalctl to a file and I can send it to you if you wish but according to last night's news the Three network failed to send the btoadcast. The file is prettty big and it might be worth me trimming it down a bit before sending, but I am away all week so I will have to do it at the weekend.
-
@lduboeuf was out yesterday. Just ran journalctl and log starts from 15:49 so after the broadcast. Any use?

humm weird. Did you use the command with grep CBS ?
But yes no interest if after 15:49 -

Ah ok, that explain. So no need to send the logs.

On P3a no emergency notification but I didn't realize I had to be on dev, my bad. In the UK it is only 4g/5g that receive the broadcast and in my networks forum a poster said only android 11 and above would work. Would that have an impact on Ubuntu Touch devices ?

The dev channel was just to have logs in case of decoding failure.
i'm surprised it needs Android 11. Cell Broadcast is a protocol that exist since 2G iirc, and already had one on the P3a. But maybe providers didn't enabled it for others than 4G/5G.
Do you also have something in logs ? -
@lduboeuf
No logs unfortunately.
I was surprised too but according to the BBC website (UK national news) - " The alerts will work on all 4G and 5G phone networks and on devices with the following software:iPhones running iOS 14.5 or later phones and tablets running Android 11 or laterOlder "non-smart" phones will be unable to receive the alerts, and nor will devices that are turned off or on aeroplane mode. "

My husband got a notification and, I'm not totally sure, but I would say he doesn't have Android 11... when he comes back I can check.
I can try to check any log if any on his device if you explain what to do
Another planet, another time, another universe!

@lduboeuf this is his Android version
