From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Could this be related to the fact that the closest Manjaro mirrors to you are in Iran, and currently down due to the Iranian government's internet block?
And Fedora has pretty bad mirror selection in general.
What you could try: run
sudo pacman-mirrors --fasttrack && sudo pacman -Syuon Manjaro, and setfastestmirror=truein/etc/dnf/dnf.confon Fedora.In my experience, dnf has pretty good mirror selection by default. Setting "fastestmirror=true" replaces the more complex mirrormanager2 heuristic, which tries to select an appropriate mirror by available bandwidth, with a simple latency check that runs before transactions. In most cases this has no effect or worsens dnfs performance. They changed the description in dnf5 to better reflect the behaviour.
Having said that, it's worth giving a try in a case like this. I just want to make sure that people realize that there is a reason this was never enabled by default, since this is a popular configuration tweak suggested all over the internet, whose actual function very few seem to know.
is there an option to disable DNF syncing and checking the latency of the mirrors every time?
dnf --cacheonlyIt only checks mirror latency every transaction if you enable "fastestmirror". Repositories are only synced if the local cache is out of date or the metadata timestamp has changed. There might be a way to prevent dnf from refreshing repository metadata at all, but I really don't think that's a good idea.
