A few weeks ago, the official Manjaro Twitter account published something that upset its users. It was a tweet that seemed normal, but ended up recommending Flatpak packages to be used less AUR, the repository of the community of Arch Linux where packages such as Google's Chrome are found, for example. There were people who replied to that tweet saying directly that they used Manjaro/Arch Linux for AUR, and it was hard to believe what we were reading, but everything has an explanation and seems to be a solution.
The principle of the explanation is that there are users who use AUR a little more. That is, they even install the software from this Arch Linux community repository before the official repositories. When requests are few, no problem, but Manjaro is not Arch Linux, and its stable branch is updated every few weeks. That's part of the problem: when Manjaro releases a stable version, many of us pull Pamac to upgrade, and Pamac upgrades everything it has available, including AUR packages. At such times, Arch User Repository suffers, and Manjaro gets a bit of a slap on the wrist.
Arch Linux and Manjaro prepare solutions
As explained in this y this other link of the Arch Linux GitLab, they are working on a new AURweb that would improve traffic management. From what we read in the second link, one solution seems to be to block Pamac's User Agent, which seems to reduce traffic by up to an eighth. If Manjaro has posted that they are working with Arch Linux, it doesn't seem likely that the solution will be a permanent lock, but rather a temporary one, probably in the days when a stable version is released. If the latter is what they decide to do, we would receive the stable updates as usual, but the AUR packages would be updated at a later time.
More extensive details are expected to be published soon, but this joint work between "father" and "son" will benefit us all.
The latest stable version of Manjaro was launched last February 27.
I consider it crazy to install all the software starting from the AUR, if you are not careful, you install software that is not kept up to date or worse, libraries that use software in the AUR that, in addition to being available, replace the existing ones installed from the official repositories, causing a program you end up updating almost daily whenever an updated version of the package (especially git versions) becomes available. I would only recommend installing software from the AUR as a last resort and replacing the official repositories with flathub, snap and appimage to avoid all possible bloatware on the system (although you can deal with orphaned packages sometimes some are used by third parties but the system insists on classifying them as orphaned packages), removing them is when it becomes the problem not to mention the increase in ram consumption.
