etesync-dav VS NextCloudPi

You can download it and find instructions here: https://github.com/etesync/etesync-dav

That is where I got the package from: linux-amd64-etesync-dav on Github

etebase is an end-to-end encrypted synchronization backend that supports, among other things, tasks. I use etesync for android in conjunction with opentasks on android and etesync-dav as a caldav gateway (synchronized to thunderbird with tbsync and its caldav backend) on the desktop. The backed is rather easy to run as a container image.

There's the official EteSync DAV that works with Thunderbird. :-)

2) install this local bridge server locally on the computer where evolution is installed : https://github.com/etesync/etesync-dav

I am using etesync-dav on Linux. You have to follow this guide https://github.com/etesync/etesync-dav First, make sure etesync-dav works on your OS. Then you have to install the add-ons Tbsync and Dav for Thunderbird and enter your local dav server adress. After restarting the PC the syncing works fine for me.

I'm also using EteSync with the etesync-dav "bridge" for synchronising calendars and contacts (even though, that happens outside of ProtonMail; for me it was more important to have the sync working with Thunderbird and Android devices.

To use the etesync-dav bridge downloads available here: https://github.com/etesync/etesync-dav/releases

Use http://localhost:37358/ for both servers, your EteSync username as the username and the DAV password you got in configuration and running as the password.

It works great and is reasonably fast if you connect it over ethernet. If you have a newer firmware, which has already enabled the boot from SSD on your pi it is super easy (otherwise just Google how to set up boot from ssd with a microSD). Afterwards you can use the raspberry pi flashing tool to flash the image of nextcloudpi on your ssd. This includes the 64bit raspberry pi OS, a running Nextcloud instance and some other handy tools (like help to set up security features). The first setup can be done with the IP adress of your Pi in an internet browser of a device in your network. Here is the link to the image of NextcloudPi https://github.com/nextcloud/nextcloudpi

Issue 2 still persists and after digging around found this issue reported on git https://github.com/nextcloud/nextcloudpi/issues/1752 but cant figure out how to sort it

Install nextcloudpi (https://github.com/nextcloud/nextcloudpi) Install Nextcloud app on your phone.

If you want to update faster than the docker image is published, you'll have to build the image locally: https://github.com/nextcloud/nextcloudpi

My best experience in out of the box comes from Nextcloudpi: https://nextcloudpi.com/

Nextcloud is functionally similar to Dropbox, Office 365 or Google Drive but is self-hosted so you are in control of your data. This version is a lightly-forked version of NextCloudPi, which was developed for SBCs like the Raspberry Pi. Only a few changes from upstream and some SysV initscripts were required to get this working nicely in Linux Deploy.
