Public bug reported:
### **Bug Report for Ubuntu 20.04 LTS: Duplicate Notifications from
Evolution Alarm Notify and GNOME Calendar**
#### **Summary**
Evolution Alarm Notify generates notifications even when the user only uses
**GNOME Calendar**, causing duplicate notifications for the same events.
#### **Steps to Reproduce**
1. **System:** Ubuntu 20.04 LTS with default **GNOME Calendar** (version
3.36.2).
2. **Evolution is NOT installed**, but **evolution-data-server** is running in
the background.
3. **Create a calendar event with a reminder** in GNOME Calendar.
4. When the reminder is triggered, **two notifications appear**:
- One from **GNOME Calendar** (expected).
- One from **Evolution Alarm Notify** (unexpected).
#### **Expected Behavior**
- If the user is **only using GNOME Calendar**, notifications should come
**only from GNOME Calendar**.
- **Evolution Alarm Notify should not start automatically unless Evolution is
installed and actively used.**
#### **Current Behavior**
- Evolution Alarm Notify **runs by default**, even when Evolution is not
installed.
- This leads to **duplicate notifications**, causing confusion for users.
#### **Temporary Workaround**
- Manually **disable** Evolution Alarm Notify by renaming its autostart file:
```bash
sudo mv /etc/xdg/autostart/org.gnome.Evolution-alarm-notify.desktop
/etc/xdg/autostart/org.gnome.Evolution-alarm-notify.desktop.bak
```
- Alternatively, users must **kill the process manually**:
```bash
pkill evolution-alarm-notify
```
#### **Suggested Fix**
- **Evolution Alarm Notify should not be enabled by default** when Evolution is
not installed.
- There should be an option in **GNOME Settings** to disable Evolution Alarm
Notify **without affecting the GNOME Calendar functionality**.
#### **System Information**
- **Ubuntu Version:** 20.04 LTS (Focal Fossa)
- **GNOME Calendar Version:** 3.36.2
- **Evolution Data Server Version:** (can be retrieved with `dpkg -l | grep
evolution-data-server`)
- **Expected Behavior:** Notifications from **only GNOME Calendar** when
Evolution is not installed.
- **Actual Behavior:** **Duplicate notifications** from both GNOME Calendar and
Evolution Alarm Notify.

### **Additional Notes**
This issue may also affect **newer versions of Ubuntu**, but I have only tested
it on Ubuntu 20.04 LTS. If confirmed, this could be relevant for future
releases.
Would appreciate feedback from the developers on whether this is an
intended behavior or a misconfiguration.
Thanks in advance for your time! 🚀
