kalarm binary package in Ubuntu Bionic armhf

 KAlarm provides a graphical interface to schedule personal timed events -
 pop-up alarm messages, command execution and sending emails. There is a
 range of options for configuring recurring events.
 .
 A pop-up alarm can show either a simple text message, or the contents of a
 text or image file. It can optionally be spoken, or play a sound file. You
 can choose its appearance, and set reminders. Among KAlarm's other
 facilities, you can set up templates to allow KAlarm to be used as a 'tea
 timer'.
