Need alarm clock popup for work

[GunsMadeAmericaFree]

I work with students at a school, and recently they started having some of our students go down and volunteer in the
cafeteria at different times, and for different lengths.

I can get involved in reading things, grading papers or working with students in the room. I need a visual reminder (jpeg image popup?),
since I typically have the sound on my Linux Mint 20 desktop muted.

I thought that perhaps this would solve my problem:

Linux Mint - Community

Linux Mint - Community

community.linuxmint.com

It seems to have an alarm that pulls up a jpeg image, but I couldn't
get the initial command line to work, which is supposed to get and install
the program: $ sudo apt-get install alarm-clock

It didn't seem to be able to find it...

Any ideas? Not sure where to go from here....

sudo apt-get install alarm-clock
is what I have typed, and it says "unable to find alarm-clock"

I'm coming from DOS, then Windows, with a very, very tiny bit of experience from years ago using a Unix Shell menu for email, (pine) and a Usenet News reader. The last few months have truly been my first regular experience with Linux.

The thread you linked to is 8 years old, that might be part of the problem.
You could try this one:

Alarm Clock Applet

Alarm Clock is a fully-featured alarm clock for use with an AppIndicator implementation.

alarm-clock-applet.github.io

It seems to work for me, but I have not tested it extensively.

I'm used to using the Linux Mint 20 software manager to install most programs. I've used the command line a couple of times when people had it listed, but don't understand it really.

In the instance above, what do we need to do to install it? I've clicked on the link, but nothing happens when I left click, and right click gives me a "page not found".

Dang, I found Kalarm in the Linux Mint software repository, installed it, and thought that it might work. It lets you choose between an audio alarm or popup alarm, which sounded great. Unfortunately, you need to set up the alarm for every single day in the future when something needs to happen. I don't see any setting for repeating, Mon - Fri, or anything like that. It appears that it would be useful to remind you of something like a birthday, but not very useful for repeated daily reminders - which was what I wanted it for, unfortunately.

If anyone can help me get that 'alarm clock applet' above installed, I would appreciate the help. I don't see that one in the Linux Mint 20 software repository.

open terminal and paste the following 3 lines will get Alarm-Clock app installed.

You can repeat the alarm.

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

Installation tested on my newly installed Mint 21 VM.

I'm a Linux newbie too.

Just enter xviewer /home/username/Pictures/children.jpg in alarm setup as custom command if you have a picture named children.jpg under Pictures folder
