Sorry, this is a misunderstanding on my part.

I saw

"Google accounts have been fixed and can now set up again properly",
.... "And a few bugs and common issues have been fixed, too."

and was of the opinion that something was fixed with the online accounts. That's why I tried "Generic CALDAV" again after a long time. I was pleased to see that this feature no longer crashes like it did in previous versions. However, appointments are still not synchronized.

@Mikaelb, I know the script solution and have used it for several months.

But, it no longer works for me with the OTA-21 RC.

In the terminal I start as part of a bash script :

/usr/bin/syncevolution kalender

and get errors with OTA-21 now. That's new! At the moment the calendars cannot be used.

The system message is

status = 20010
error = error code from SyncEvolution error parsing config file (local, status 20010): kalender: backend not supported by any of the backend modules (syncxmlrpc, syncsqlite, syncqtcontacts, syncmaemocal, synckcalextended, syncfile, syncecal, syncebook, syncdav, syncactivesync , platformgnome) or not correctly configured (backend! 3dselect backend databaseFormat! 3d syncFormat! 3d)

end = 1641012600, 2022-01-01 05:50:00 +0100

Edit :
Status 20010 could be : 20010 Error parsing XML config file

Generic CALDAV? with Nexus 5

I am using a local CALDAV server with Ubuntu Mate (radicale server) and cannot sync my calendars. Radicale works as it should. I have been using my own calendar server successfully with all devices for years.

What I do....
I add an internet calendar and select Generic CALDAV. After entering the local address ("192.168.x.x: 5232/username/") my 4 calendars and 1 address book are found and displayed. All 4 calendars are marked for viewing.
Furthermore, the account has been set up, seen and activated in the settings (com.ubuntu.calendar/calendar).

The synchronization can be started manually and seems to be doing something, but there are no appointments to be seen in the calendars. I was hoping that CALDAV would now work with this release candidate. Is there a log file that I can view and where can I find it?

If someone has a similar problem, I would be grateful for advice.

I flashed an old Xperia X Compact with a fresh OTA 16. The original battery (old, I know) has to be charged in the evening after a day of idling. For a 2700 mAh battery, that's disappointing. Is it worth buying a new battery and what runtime can I expect? Does anyone have any experience?

@unrealb2 I took a similar way for testing purposes via TWRP and flashed LOS 16 (Droid 9) onto the X Compact. What can I say, the same device with the same battery only consumes 1.2-1.5% per hour and thus like my Nexus 5. UT seems to have a problem with the Xperia? Factor 10 per hour in consumption, that is useless. I will try OTA 17 again. If that also has this high consumption, it will stay at LOS 16.

@unrealb2 said in How's the battery life experience in an Xperia X Compact?:

but it crashes on push. Any advice on how you got it?

No I'm sorry. I had no problems.

@messayisto Hmm, that doesn't sound good. For me it is 10-15% per hour when it is idle. Nevertheless, thanks for the information. I have now discovered a second problem. The device is SIM lock free and only accepts one of 3 new SIM cards. The other two are not detected?!. That is hard.

@unrealb2 said in How's the battery life experience in an Xperia X Compact?:

Does it video record? Anything you like or dislike about it?

What should I say, it's a phone! Video works very well with the front and rear cameras. I like this phone because it's small and OTA 16 runs on it with no problems. I haven't tested all functions yet.

But I already have one negative point: the battery is difficult to replace.

Hmm, I am asking because my Xperia XA2 with Sailfish does not ping the world after a fresh installation and initial setup without installed apps. It's just quiet and doesn't connect to anyone while idle or in flight mode. Compared to the XA2, the N5 is surprisingly talkative.

OK, it's what it is. I just wanted to know. Thanks for the hints.

User in another forum was asked why Ubuntu Touch connects to Canonical and UBPorts every few minutes. The network traffic was measured with tcpdump. This behavior should be able to be observed with a fresh system without additionally installed apps and occurs when the system is idle. Is there an explanation for this? I'm interested in that too.

Initially some ntpserver belonging to Canonical are queried and

0.push.ubports.com.https.

Thereafter, further calls are made periodically every few minutes:

• cactuar.canonical.com.http
• davybones.canonical.com.http
• 0.push.ubports.com.5001

I would expect UT do not open any external connections when idle. It would save the battery and the data plan. What is it good for??
