Why? I gave the guy an answer in the comments…

max_parallel_downloads: This parameter specifies the maximum number of packages that DNF can load in parallel. The default value is usually 3 or 5, depending on your system. Decreasing the value: By decreasing the value of max_parallel_downloads, you will force DNF to load packages sequentially or in smaller groups. For example, by setting max_parallel_downloads=1, you will effectively disable parallel downloading and DNF will only download one package at a time. Speed Impact: Reducing max_parallel_downloads will cause the update process to slow down. In conclusion, reducing max_parallel_downloads is a perfectly logical way to reduce the number of DNF packages being loaded in parallel. Just be aware of the impact on speed and test different values to find the best one for your conditions.

I just suggested options but also wrote at the end that it depends on interests and actions

upgrade and update are the same thing, to put it simply, because they are needed to download new versions of programs or so that you can install fresh updates and the latest versions of applications. update — updating the list of packages. upgrade — updating the packages themselves.

ubuntu,debian - for beginners. fedora,garuda - average. arch,blackarch,kali linux - for experienced. But do not forget that the distribution depends on your interests and actions.

Fedora Kinoite / Silverblue,Xubuntu / Linux Lite / Zorin OS Lite,KDE Neon / Kubuntu, Arch + KDE / Arch + Sway or Hyprland. Wacom / Synaptics / AES styluses - usually recognized by the Linux kernel. KDE - provides profiles for stylus, pressure, buttons, sensitivity. Gnome (on Wayland) - recognizes styluses, but with less customization.

Probably my answer will not concern what I will tell about the program, but about what I liked about Linux, that there is freedom of action and everything is under my control
