Calendar and Addressbook (Radicale)
With Radicale, you can synchronize your personal calendars, ToDo lists, and addressbooks with your various computers, tablets, and smartphones, and share them with friends, without letting third parties know your personal schedule or contacts.
Why should I run Radicale?
Using Radicale, you can get rid of centralized services like Google Calendar or Apple Calendar (iCloud) data mining your events and social connections.
How to setup Radicale?
First, the Radicale server needs to be activated on your box.
- Within Plinth
go to Calendar and Addressbook (Radicale) and
install the application. After the installation is complete, make sure the application is marked "enabled" in the FreedomBox interface. Enabling the application launches the Radicale CalDAV/CardDAV server.
- define the access rights:
- Only the owner of a calendar/addressbook can view or make changes
- Any user can view any calendar/addressbook, but only the owner can make changes
- Any user can view or make changes to any calendar/addressbook
Note, that only users with a FreedomBox login can access Radicale.
If you want to share a calendar with only some users, the simplest approach is to create an additional user-name for these users and to share that user-name and password with them.
Radicale does not have a user interface. An external supported client application is needed.
Now open your client application to create new calendar and address books that will use your FreedomBox and Radicale server. The Radicale website provides an overview of supported clients, but do not use the URLs described there; FreedomBox uses another setup, follow this manual. Below are the steps for two examples:
- Example of setup with Evolution client:
- Create a new calendar
- For "Type," select "CalDAV"
- When "CalDAV" is selected, additional options will appear in the dialogue window.
URL: https://IP-address-or-domain-for-your-server/radicale/user/calendar-name.ics/. Items in italics need to be changed to match your settings.
note the trailing / in the path, it is important.
- Enable "Use a secure connection."
- Name the calendar
- TODO/Tasks list: Adding a TODO/Tasks list is basically the same as a calendar.
- Follow the same steps described above and replace CalDAV with WebDAV. The extension of the address book will be .vcf.
Synchronizing with your Android phone
There are various Apps that allow integration with the Radicale server. This example uses DAVx5, which is available e.g. on F-Droid. If you intend to use ToDo-Lists as well, the compatible app OpenTasks has to be installed first.
Follow these steps for setting up your account with the Radicale server running on your FreedomBox.
- Install DAVx5
- Create a new account on DAVx5 by clicking on the floating + button.
Select the second option as shown in the first figure below and enter the base url as https://<your.freedombox.address> (see the first screenshot below). DAVx5 will be able to discover both CalDAV and WebDAV accounts for the user.
Follow this video from DAVx5 FAQ to learn how to migrate your existing contacts to Radicale.
- Click on the hamburger menus of CalDAV and CardDAV and select either "Refresh ..." in case of existing accounts or "Create ..." in case of new accounts (see the second screenshot below).
- Check the checkboxes for the address books and calendars you want to synchronize and click on the sync button in the header. (see the third screenshot below)
Above was shown an easy way to create a resource for a group of people by creating a dedicated account for all. Here will be described an alternative method where two users User1 and User2 are granted access to a calendar. This requires SSH-access to the FreedomBox.
create a file /etc/radicale/rights
[friends_calendar] user: ^(User1|User2)$ collection: ^.*/calendar_of_my_friends.ics$ permission: rw # Give write access to owners [owner-write] user: .+ collection: ^%(login)s/.+$ permission: rw
[friends_calendar] is just an identifier, can be any name.
The [owner-write] section makes sure that owners have access to their own files
edit file /etc/radicale/config and make the following changes in section [rights)
[rights] type = from_file file = /etc/radicale/rights
Restart the radicale server or the FreedomBox
If you are using a contacts file exported from another service or application, it should be copied to: /var/lib/radicale/collections/user/contact file name.vcf.
Migrating from Radicale Version 1.x to Version 2.x
During the month of February 2019, radicale in Debian testing was upgraded from version 1.x to version 2.x. Version 2.x is a better version but is incompatible with data and configuration used with 1.x. Automatic upgrade mechanism in FreedomBox, handled by unattended-upgrades does not automatically upgrade radicale to version 2.x due to changes in configuration files. However, FreedomBox version 19.1, which is available on February 23rd, 2019 in testing will perform data and configuration migration to radicale version 2.x. Typical users require no action, this will happen automatically.
If for some reason, you need to manually run apt dist-upgrade on your machine, then radicale will be upgraded to 2.x and then FreedomBox will not be able to perform its upgrade (due to upstream project deciding to remove migration tools in radicale 2.x version). To avoid this situation, the following process is recommended if you wish to perform an upgrade.
sudo su - apt hold radicale apt dist-upgrade apt unhold radicale
However, if you already happen to perform an upgrade to radicale 2.x without help from FreedomBox, you need to perform data and configuration migration yourself. Follow this procedure:
sudo su - tar -cvzf /root/radicale_backup.tgz /var/lib/radicale/ /etc/radicale/ /etc/default/radicale apt install -y python-radicale mkdir /root/radicale-migration python -m radicale --export-storage=/root/radicale-migration cp -dpR /root/radicale-migration /var/lib/radicale/collections/collections-root/ chown -R radicale:radicale /var/lib/radicale/collections/collections-root/ apt remove -y python-radicale if [ -f /etc/radicale/config.dpkg-dist ] ; then cp /etc/radicale/config.dpkg-dist /etc/radicale/config ; fi if [ -f /etc/default/radicale.dpkg-dist ] ; then cp /etc/default/radicale.dpkg-dist /etc/default/radicale ; fi (After FreedomBox 19.1 is available, goto FreedomBox web interface and set your preference for calendar sharing again, if it is not the default option, as it will have been lost.)
python-radicale is an old package from radicale 1.x version that is still available in testing. This is a hack to use the --export-storage feature that is responsible for data migration. This feature is not available in radicale 2.x unfortunately.
- Files ending with .dpkg-dist will exist only if you have chosen 'Keep your currently-installed version' when prompted for configuration file override during radicale 2.x upgrade. The above process will overwrite the old configuration with new fresh configuration. No changes are necessary to the two configuration files unless you have changed the setting for sharing calendars.
- Note that during the migration, your data is safe in /var/lib/radicale/collections directory. New data will be created and used in /var/lib/radicale/collections/collections-root/ directory.
- The tar command takes a backup your configuration and data in /root/radicale_backup.tgz in case you do something goes wrong and you want to undo the changes.
