Alarm Clock is a fully-featured alarm clock which resides in the notification area. It is easy to use yet powerful with support for multiple and repeatable alarms, as well as snoozing and a flexible notification system.

Two types of alarms are supported: Alarm Clocks and Timers. Notification is done by either playing a sound or launching an application.

This software is not available in the official repositories. The developers recommend using their official PPA.

sudo add-apt-repository ppa:tatokis/alarm-clock-applet
sudo apt update
sudo apt install alarm-clock-applet

This package has a complete graphical front end with which a user can set an alarm to wake the computer - from poweroff if possible - and read a user-defined text. This text can grab relevant information (date, time, weather, Evolution schedule and tasks, news from an rss feed, number of new email messages, etc.) and speak that as well, or play music, all as defined by the user. More capabilities can be added to the alarm via a complete and simple plugin system. Supports multiple alarms.

Answer 5

To install alarm-clock-applet in Ubuntu 22.04: https://packages.ubuntu.com/bionic/amd64/alarm-clock-applet/download. I downloaded the amd64 architecture for my system: alarm-clock-applet_0.3.4-1build1_amd64.deb.

$ sudo apt-get install ./alarm-clock-applet_0.3.4-1build1_amd64.deb

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 alarm-clock-applet : Depends: gconf-service
                      Depends: libappindicator1 (>= 0.4.90)
                      Depends: libgconf-2-4 (>= 3.2.5) but it is not installed
                      Depends: libunique-1.0-0 (>= 1.0.0) but it is not installed
                      Depends: gconf2 (>= 2.28.1-2)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
$ sudo apt-get --fix-broken install

"Alarm Clock" application should now be available to run.
