DavDroid Crashes when adding a nextcloud account

Kongwak: A solution to davdroid crashes on android

== Problem Description ==

Davdroid crashes when trying to create your nextcloud/opi account to sync Calendar and Contacts (Caldav/Carddav) on an Android phone. Your account can not be saved.

This issue occurred for me when I updated my old opi to the kinguard software and tried to sync the new calendar/contacts using davdroid instead of the old opi apps. I had reused the machine name and admin account for the new install.

== Issue ==

This appears to be an issue with the android online account manager not liking having accounts with very similar credentials.

== Solution ==

To resolve this, go to the android accounts (settings -> accounts) and delete any old opi accounts.

Delete the the old opi applications

Shutdown and restart the phone.

Hopefully this will resolve the problem.

Kongwak: link to img writing tool = etcher

== Current release ==
The current release for The Kinguard Project is "Kinguard 18.06".

=== Install images ===
Install images are provided on the Kinguard [https://www.kinguardproject.org/download/releases/18.06/ Download Area] for both OPI and KEEP.

Please read the [https://www.kinguardproject.org/download/releases/18.06/ReleaseNotes_18.06.pdf ReleseNotes].
=== How to install ===
For KEEP write the img-file to a USB stick and press and hold the button for 10 seconds while inserting power.

A simple cross platform tool to write .img files to an SD Card or USB Stick is Etcher. https://etcher.io/

For KEEP, the installation takes about 3 minutes. Unfortunately there is currently no visual indication that the installation has completed. A hint though is that when the harddrive spins down, the installation is complete. After the completed installation the unit needs to be power cycled.

For OPI write the imate to a uSD card, insert it into OPI and apply power.
OPI will turn off all LEDs when the installation is complete.

If data is to be restored from a backup, the recommended way is to make sure that a backup on USB exists (usually faster than downloading from on-line servers), make a clean shutdown of OPI and then leave the USB memory inserted during the setup. The data set can then be chosen during the "Restore" step of the setup procedure.

=== Installer Configuration ===
In the installer image there is a configuration file that can be used to alter the behavior of the installer image.

In "/etc/kgp-install.conf" there are few parameters avaialbe:

DO_INSTALL=1

By default this parameter is set to "1", which will cause the image to basically do a factory reset by formatting the internal eMMC and reinstalling system software. Any data on the data disk will be left intact.

DO_ADDROOT=0

By default this parameter is set to "0". By changing this to "1", the system will be installed a root account is added with the password "op237".
This is only available on the serial port, ssh is not enabled by default.

How to connect to the serial port is described [[Enable serial console|here]].

== Older releases provided by OpenProducts ==

=== OPI ===

[https://download.openproducts.com/opi/rescue/ Rescue images]

Instructions on how to reinstall is available [https://www.kinguardproject.org/forum/viewtopic.php?f=345&t=466 here]

The rescue image is very similar to the install image, only that the image does not re-install the system. The system will be available both on the serial port and on ssh with the user/password of root/op237. The root file system can then be accessed and manipulated, but all user data is only available if the encrypted partition in unlocked and mounted by hand.
