Well, Gnome 45 is in extra now. That was unusually fast!

I would assume that “market share” is related to the relative number of units sold/number of active subscriptions/fraction of total sales in terms in revenue, or some similar metric. I run a variety of different distributions on servers (bare metal, VMs and containers) and desktop computers. Do they all count equally? Without giving it more thought, I wouldn’t even know how to determine the market share of Ubuntu in my own home in a sensible way.

With Windows, I can just count the number of active licenses. Oh wait, its zero.

With version 45, Gnome switches to ECMAScript modules (ESM). This standardizes javascript exports/imports, but it also means that every single extension will have to be adjusted to work with Gnome 45. I would not mind if Gnome 45 stayed in testing for a bit longer, so developers have time to adjust.

pacman -Qqdt will list the obsolete packages without the version number. You can pass the output of this command (i.e. all the obsolete packages) back to pacman using $(…) command substitution: sudo pacman -Rns $(pacman -Qqdt)

You can list the packages that were previously installed as a dependency for another package but are no longer required using pacman -Qdt. It should be safe to remove all of them. (Some of them might only be required to build another package from the AUR, not to use it. But those will automatically get reinstalled the next time you update/install that package using paru).

You can automatically remove all obsolete dependencies when uninstalling a package using pacman -Rns . For example, pacman -Rns wine would have likely uninstalled the lib32-… packages for you automatically (assuming no other package depends on them).

You installed these packages using the multilib repository (anything lib32-… lives in there, and a few other packages). Now, for whatever reason, the multilib repository is no longer available. Maybe you deactivated it in your pacman configuration, or you just had issues downloading the latest package database. paru no longer finds them in the official repositories, and it also does not find them in the AUR, so it displays that message. After you have updated/reenabled the multilib repository, this message will disappear.

I don’t have that README.zst file in Ubuntu 22.04 LTS, but the amd64-microcode version is 3.20191218.1ubuntu2. The package source code should be here (The server has not rebooted since the last package update).

$ grep "\(microcode\|model name\)" /proc/cpuinfo | head -2
