In the absence of Ralphy's customized version of the Mint Updater tool for Linux Lite, you can still run a version of the updater (not Ralphy's, though) courtesy of the Mint Tools website -
https://launchpad.net/~gm10/+archive/ubu...mint-tools
Just add the ppa using the command line (terminal) with the following -
sudo add-apt-repository ppa:gm10/linuxmint-tools
sudo apt-get update
After adding the ppa, open Synaptic Package Manager and search for 'mintupdate'. Install and then reboot your system.
You can run the Mint Updater either through the whisker menu or by clicking on the 'shield' icon in the panel. If the shield icon doesn't appear automatically in the panel after rebooting your system, just add the item 'Notification Area' to the panel to make it appear.
And that's it - not as slick and as integrated as Ralphy's version (no colored shield icons, for instance) but it does run on LL.5.
For the lazy updater, there is also a great bash tool called Ucaresystem-core. You can download the .deb file from the app website -
https://launchpad.net/~utappia/+archive/.../+packages
Choose the ucaresystem-core_4.4.0_all.deb (23. KiB3) package file for 'Focal' and save it to downloads in your file manager.
Once you've installed the file using gdebi, you can run Ucaresystem-core either as a GUI app or open a terminal and just type 'ucaresystem-core', it's that simple.
After updating your system, Ucaresystem-core will not only automatically remove old, unneeded kernels, but it will also check to see if you need to reboot your system after installing updates. It's one of my favorite apps.
Enjoy
