I'm installing Ubuntu Mate since 4 years, for old peoples. Because it's the only Ubuntu flavor which can mimic layout of Windows 7/10 and can really lock the panel with the command:
gsettings set org.mate.panel locked-down true
Unfortunately, as many old peoples have this very sad issue, I can no more install Ubuntu Mate for old peoples. They are just not able to understand to reboot their machine to bring back the menu and the indicators, in a lucky day.
This is the second big issue for old peoples in addition of my other topic about menu broken after upgrade from 20.04 to 22.04 with Redmond layout with Dock applet.
