@ant thank you.
@korealinux I think my system is stable. I have had no reboot errors, long since that change to Stable.
Reinstalling several times (like it is not a big deal,) is for those who like playing with their OS as a hobby, (I feel.) Perhaps a normal thing for those specializing in computer technology.
I use an OS to get daily work done.
With the help of many, I am learning as I go so that I can maintain a good work-computer which I can rely upon.
I have not had issues since making sure I was on a Stable channel. I have done several little updates since then with NO issues or key signature problems. Then I do this update and I get into very unstable waters.
While it is possible all of this came from previous or remaining issues, like ghosts, I think it may just be a simpler issue of the whole key updates issues which seem documented by many!
So, I appreciate your obvious knowledge and decision to respond and perhaps help, it seems you are trying very hard to concentrate on past solved issues, versus taking my (acknowledged limited experience) perception, and working to figure out a well-defined process for stable updates with checks and validations to make the updates simple.
When a STABLE release is pushed such that the OS alerts the user of xxx updates available, there should be other background processes that make sure proper preparations are in place so that the updates, when triggered, are applied in a good environment.
If the system can see that keys are a problem, that should be resolved or at least flagged, before a button-push builds upon problems. Am I crazy for thinking this is a valid, logical approach?!
If you can't see that as a reasonable suggestion to help make Manjaro better, then what are you intending to respond with?
I honestly mean it. If you see a current issue with my system that suggests it is NOT stable, please tell me what it is, so we can get to fixing it. If not, please turn your obvious ability to make the update process better. I know I can't! So, I hope people like you do. If you can get me in touch with you privately, I would be happy to fund some of that good work, since I lack the knowledge, experience, and ability to do it myself to improve this good OS.
