I was able to set up my carddav and caldav accounts like this:
https://docs.ubports.com/en/latest/userguide/advanceduse/dav.html

And I was able to delete wrong configurations like this:
https://forums.ubports.com/topic/7092/delete-a-calenendar/5?_=1643577988544

Unfortunately, I noticed that changes were not uploaded. If I understand correctly, this is what cron would be for.

Shouldn't these lines in the script dav.sh be the ones responsible for this? Is there something wrong with it?

How does that work properly?

#Add Sync Cronjob
sudo mount / -o remount,rw
COMMAND_LINE="export DISPLAY=:0.0 && export DBUS_SESSION_BUS_ADDRESS=$(ps -u phablet e | grep -Eo 'dbus-daemon.*address=unix:abstract=/tmp/dbus-[A-Za-z0-9]{10}' | tail -c35) && /usr/bin/syncevolution $CALENDAR_CONFIG_NAME && /usr/bin/syncevolution $CONTACTS_CONFIG_NAME"
sudo echo "$COMMAND_LINE" > /sbin/sogosync
sudo chmod +x /sbin/sogosync

CRON_LINE="@$CRON_FREQUENCY /sbin/sogosync"
(crontab -u phablet -r;) # only if no other cronjob already exist in the crontab
(crontab -u phablet -l; echo "$CRON_LINE" ) | crontab -u phablet -
sudo mount / -o remount,ro
sudo service cron restart

I haven't gotten that far, and I'm not yet able to use my passwords with Unix Pass on my Ubuntu Touch device, which currently forces me to always have two phones with me.

Is there something I am doing wrong? I was able to initialize the program with pass, but I can't generate and save passwords. Its generating one but the list remains empty. Among many 'libtls-padding.so' errors.

@stanwood You write: It is strongly not recommended to use apt to install software. (as it won't work and may brick your device)
But back to the main topic. How do I do it? Even if it may brick my device. Better than no device. That would be the case if a such a simple thing like pass do not work on a ubuntu-phone.

@nero355 @arubislander
Thank you! Developer mode was on. (Might be a bit hidden in my original post). So in "normal case" the phone should become visible for adb as soon as developermode is active.

@applee Works fine with ssh, except that I have to put my passphrase maybe 20 times..
So if someone has an idea how to do it with cable, would simpler. I know I could skip the passphrase forever, but this is not what I want
What I am asking myself: adb is android debug bridge, so on a phone without android, can there be a adb?

@applee The cable should be correct.. I could also mount the files on ubuntu. Ok, I will try with ssh, which is configured. But I thought the cable should be faster. If there is a way with cable, I would prefer it.

@moem Its a volla phone x

I was following the instructions here.

After creating my first app (called testytest) i run:

cd testytest/
clickable

and got the message at the end:

Cannot access device.
ADB: No devices attached
SSH: no IP address specified (--ssh)

Developer mode was on.

adb devices

Gave me no result. I have just an Ubuntu-Touch an no Android system on my phone. So is there adb available? Do I have to install it somehow? Or activate?

@stanwood What I did is now:

#!/bin/bash
# create the container:
libertine-container-manager create -i pcapps -n pcapps
# install pass
libertine-container-manager install-package -p pass

I copyed also all my encrypted passwords to /home/phablet/.password-store
Then executed:

libertine-launch -i pcapps pass

Now I got the following:

ERROR: ld.so: object 'libtls-padding.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object 'libtls-padding.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
: DISPLAY environment variable not set!
ERROR: ld.so: object 'libtls-padding.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
Error: password store is empty. Try "pass init".

Also I tried to copy the passwords to:

~/.cache/libertine-container/pcapps/rootfs/home/

No success.. Where do I have to copy them? Or in other words: Where is the home which sees the program in the container?

@totalsonic Thanks steve! I will try that.

@stanwood Thanks... It's a pity that this is exactly the kind of thing I find so cool about Linux. That you have a packet manager, and the programs can use each other.
Is a program via the Openstore also accessible in the console?
So is there an other way to install for example pass on my device?

Hello all!
I am not the super programmer but would like to try. I tried

sudo apt install pass

and got:

E: Unable to locate package pass

Since the program is pass opensource, it should not be very complicated to compile it for ubuntu-touch and add it to the repo. However, I have never done this before. How can I proceed?

Or do I just need to add a repo? Maybe someone has already done this?

@gy0im Thanks that did the trick.. I did not know what I was deleting actually, and by mistake I also deleted my phone book. But nothing I can restore, so everything great!

So far I tried to install caldav and carddav on ubuntu touch without success.
I tried like this:
https://docs.ubports.com/en/latest/userguide/advanceduse/dav.html

But now the question:

I have now 2 calendars in my list (duomimocal), which I cannot use. How can I delete them?

@guf Hmm... I tried to write everything above what I did. Doesn't the Halium script copy the data to the partition? Do I need another command in between?
Something like

fastboot flash datapart system.img
fastboot flash datapart rootfs.img

You can probably see my lack of knowledge in context. That's why it's difficult for me to successfully install UT from the forum. I can learn a lot from manuals.

@metty Without knowing exactly what I did: I did the same as here , from @franky32: Uncomment the Line with

[ -f "$IMAGE_DIR/system.img" ] && sudo resize2fs -p -M "$IMAGE_DIR/system.img"

from core.sh in the "function-folder".

The halium-install-script finishes sucessfully, also the fastboot-flash with halium-boot-bluetooth. But the phone fails to boot.
If there are some ideas what to do here, would be happy

@keneda Oh, words are always so ambiguous Without Cover:

With Cover:

The scratch is also visible...

@keneda Back again: I replaced the display with another fair-phone which had a broken electronic, but a display who was still fine. Still without cover I was able to swipe. Now I do not know, if it really was the display or the fact, that the cover border may influence the display sensor a little bit. So my problem with the "long swipe" seems to be solved. Thanks to everyone who helps improving ubuntu touch!

@keneda hmm.. so not the scratch. I thougt the Fairphone2 is for sure a phone were many peoble would have had and solved the same problem. But actually this ist the only forum I found with information about this problem.
Is there a way tho access the rootfs through usb?

Hello everybody

This is still an old post, but I got the same problem here with a fairphone 2. The display has a small scratch, so in my case it could be a hardware issue. But still the display is working fine with android. Is there a way to avoid this introduction or message? It seems, that i have no access to the file system (or I don't know howto). Also Locking, wait a few minutes an unlocking again did not help. Also reboot has no effect. Would be nice to have some "skip-Button" for future releases. A pity that this function blocks my phone now.

@guf Thanks for resuming, that helps me a lot! And also thanks for your contribution on ubuntu-touch! Sorry for the late reaction: did not saw, that someone was answering. I have to check my Notification-Settings here.

So my starting point was, a LG-G6 without any system but twrp still runnig.

1. So I started the phone into bootloader, and connected the computer
2. Downloaded the halium install script from: https://gitlab.com/JBBgameich/halium-install/
3. Downloaded the OS from here: https://drive.google.com/file/d/1BtVYvabN0nK1bR-7Hv8kBC-CIcN-B8Rc/view?usp=sharing
4. Downloaded the Halium reference rootfs from here: https://ci.ubports.com/job/xenial-hybris-edge-rootfs-arm64/lastSuccessfulBuild/artifact/out/ubuntu-touch-hybris-xenial-edge-arm64-rootfs.tar.gz
5. Executed: ./halium-install -v -p ut ~/Downloads/ubuntu-touch-hybris-xenial-edge-arm64-rootfs.tar.gz ../system-20200326.img

I got:

simg2img not found in $PATH
make sure you have all dependencies installed.
dependencies: qemu-utils binfmt-support qemu-user-static e2fsprogs sudo simg2img binutils

So i did:

sudo apt install qemu-utils binfmt-support qemu-user-static e2fsprogs sudo simg2img binutils

After this I got:

Scanning inode table          resize2fs: No space left on device while trying to resize .halium-install-imgs.OKVWa/system.img
Please run 'e2fsck -fy .halium-install-imgs.OKVWa/system.img' to fix the filesystem
after the aborted resize operation.
I: Cleaning up
* daemon not running; starting now at tcp:5037
* daemon started successfully
error: no devices/emulators found

fastboot devices gives me:

LGH870ed0cffee  fastboot

What can I do to avoid this error?
