Thanks for the reply. Yes, I understand the whys of it. In my recent post "Making choices on old repositories" I explained how I changed from testing to stable, and how pleased I am that the new system is working fine, minus this one small glitch I've found so far. In fact, it's a workable system and I don't mind handing over this computer as is, but, even though you'd never guess it looking at the state of my kitchen, I'm kind of a perfectionist when it comes to computers. So my question was, more about the hows. When I try to uninstall sparky6-apt I get a strong warning not to do it unless I know exactly what I am doing, which I don't, so I'm asking here. It doesn't upgrade but that also doesn't break the upgrading process for other apps. How can I safely eliminate it?
Thank you pavroo for all the great effort you've obviously made over the years on this distro.
