I am also interested in supporting VoLTE-development with a donation. Is there any special equipment needed? Or something that needs to be done by a company? Or anything else that could be founded by the community? If someone working on VoLTE for UT is reading this maybe describing the current state and specific problems would be great.

@MrT10001 I am using Windows.
@beyolf Thank you for the advice. Now the installation worked. This is how I did it:

I let the installer run again until the installer stopped at "Rebooting to fastbootd". I manually updated two optional drivers in the Windows Update settings. They are called:

• LeMobile - Other hardware - Android Composite ADB Interface
• LeMobile - Other hardware - Android Bootloader Interface

After the installation of these two drivers finished the installation process finished automatically.

I don't know if both drivers were necessary or if one of them would have been enough.

Thank you for everyone who answered here.

@JohnB said in Status of VoLTE (Voice over LTE 4G) implementation?:

I found an active open source bounty website that supports multi-user bounties, and talked to them in their discord

Thank you for that work!

I think this is a setting where a lot of small bounties could add up

I am not a programmer. Do you have an idea of how exactly these "small bountys" could look like?

I tryed using this way, DO NOT TRY YOURSELF, I MAY HAVE DAMAGED MY INSTALLATION:

# make the root file system writable
sudo mount -o remount,rw /
# copy certificate
cp /home/.../nextcloud.pem /usr/share/ca-certificates
# run this command
dpkg-reconfigure ca-certificates

I tinkered around a little bit and moved the certificate between /usr/share/ca-certificates and /usr/share/ca-certificates/mozilla. I also renamed it "nextcloud.pem", "cert.pem" or "nextcloud.crt".

After the dpkg-reconfigure ca-certificates there is a question shown if I want to trust the new certificates. The answer-options are "yes", "no" and "ask". I ran the command multiple times. Sometimes I choose "yes", sometimes "ask". The next page shows a list with all the certificates. Unfortunatly the screen is croped and I can't read all the text. But I can select my new certificate.

I tryed navigating to https://192.168.x.x:1234 (my nextcloud instance) in the morph-browser to check if there is a warning about an untrusted certificate. Unfortunatly there still is. And additionally sudo dpkg-reconfigure ca-certificates now shows the error message /usr/sbin/dpkg-reconfigure: ca-certificates is broken or not fully installed and exits after the error.

I am not sure where I went wrong with my tinkering. Any Ideas of how to repair the damage in the sudo dpkg-reconfigure ca-certificates?

@arubislander That my be the problem.

Is there a way to trust a certificate in UT? I found ths 4 years old thread:
https://forums.ubports.com/post/16216
Is there a better way of trusting a certificate by now? Or could I use a trusted certificate on my local server?

@zlamalp Did you have any trouble with your method of trusting the certificate of your nextcloud server?

@TheBird Thank you for your answer. Good to know that the deprecation warning does not matter.

If I type http://192.168.x.x in my browser I get "Error: net::ERR_CONNECTION_REFUSED". https://192.168.x.x leads me to the nextcloud login page. So I think 192.168.x.x is my "base url". I now tried ownCloud, Nextcloud and Generic CalDAV with http://192.168.x.x and https://192.168.x.x. If I choose ownCloud or Nextcloud I get an error saying that the host-URL is invalid and I can't create the account at all. With Generic CalDAV I can create the account but the calender does not sync.

I synced my new phone with my old nextcloud server. I noticed that my old nextcloud server is reachable through http and https while my new one is only reachable via https. I am only in my local network so https is not that important. Are there any known issues with CalDAV and https on UT?

Additional info:

With the command account-console list I can find out the id of the currently existing account (28). If I type account-console show 28 into the terminal I get the following text:

account: id 28, enabled, provider: generic-caldav
Global settings:
/usr/bin/account-console:244: DeprecationWarning: Accounts.AccountSettingIter.next is deprecated

What does this deprecation warning mean?

Hello everyone,

I am trying to set up my calendar on my UT-Fairphone 4 OTA-2 stable. I have a nextcloud calendar running that syncs with no problems with my thunderbird calendar. But I can't get the calendar to show up on ubuntu touch. My phone and the server are both in the same network.

I had a running setup with a different nextcloud server and a Fairphone 2. From that I remember, that I had to use"Genereric CalDAV" instead of "Nextcloud" in the calendar-account settings.

I tried the stup with the following URLs already because I think in the past the URL was the problem:
http://192.168.x.x/remote.php/dav
https://192.168.x.x/remote.php/dav
http://192.168.x.x/remote.php/dav/calendars/"Nextcloud-username"/"Calendar-name"
https://192.168.x.x/remote.php/dav/calendars/"Nextcloud-username"/"Calendar-name"

I always get a notification-popup that says that the sync finished. If I use https the popup apperas nearly instantly. If I use http it takes a few minutes. No appointment is shown in the calendar. The CalDAV-account is listed in the phones settings. In the calendar-app overview of calendars my nextcloud-calendar is not listed.

Does anyone know what I am doing wrong? I remember that it was a lot of work setting up the calendar on the Fairphone 2 but somehow now I can't get it to work at all with the FP4.

Thank you in advance.

@arubislander I've seen that already too. But my question/problem is still the same:
Why does the UBports Installer (0.10.0) stop at "Rebooting to fastbootd" when the device successfully boots into fastbootd? I am using a fairphone 4.

Hi @biba,
sorry for answering to this old thread but I have a similar problem. Did you find a solution for this problem?

Does anyone know where in the world I could currently use my UT-Device to make a call? In which countrys is VoLTE absolutely needed to make a call? In which countrys will 2G/3G be turned off in near future so that VoLTE will be the only option?
Is there a map or a table that shows the different available networks worldwide and maybe even planed dates for turning of 2G/3G?
