Ubuntu 21.10 upgrade went without a glitch... except gnome

cn flag

As usual the 21.10 upgrade caused the loss of all gnome-shell extensions, which in plain English means that ALL the customization of my desktop will have to be done all over again starting from scratch. Now I am stuck with a tweaks tool that does not have anything in the gnome-shell box and no extensions tab in the menu. Hovering with the mouse over the gnome-shell triangle (yes the one with the exclamation mark) informs me that the 'shell user-theme extension' is not enabled. Why I should have to enable the blessed thing together with a dozen extensions that worked fine as of yesterday... (and how I am supposed to do it)... is anybody's guess.

The upgrade took about 30 minutes and went without a glitch and now I have already wasted a couple of hours trying to figure out how to fix this broken desktop.

What am I supposed to do?

Found this article that explains it all and my gnome desktop is pretty much back to where it was yesterday: https://ubuntuhandbook.org/index.php/2021/05/gnome-tweaks-40-no-longer-manage-extensions/. This actually reminded me of something I thought: what['s the point of this tweaks tool when we have something called settings that should have all the tweaks Joe User is ever going to need... So I says to meself.... why not another tweaks-tweaks tool that lets you tweak the tweaks... Well now we have it: it's called 'extensions'!

No need to file a bug... Perhaps the ubuntu team who appear to have done a fantastic job otherwise should have put some kind of full screen warning on the do-release-upgrade screen pointing users of the gnome-based flavour of ubuntu that they should/must take a peek at the article I linked in my above comment.

Found the solution in the ubuntu handbook: if you run into this same issue please read the entry titled: Gnome Tweaks 40 No Longer Manage Extensions, Use This Tool Instead. Tells you everything you need to do...

In a nutshell: one needs to fire up something called 'extensions': just open the application search box at the top of the screen by pressing <Super> and type e x t . . . and you should see and icon that looks like a green puzzle piece and take it from there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
