Pacman randomly stops while downloading, no error messages given.

Hello there,

I've been dealing with this problem for quite some time. I have to run 'pacman -Syu' like five times every time, each time removing the db.lock manually, as it doesn't unlock itself after this crash, until it finally succeeds. My typical output of pacman looks like this:

jonaash ~ 
> sudo pacman -Syu

Just a sudden stop, no error, no nothing. No internet disconnect at this time either. I even tried turning the wifi router off and back on, which didn't interrupt it, so that can't be it.

Even when I use the --debug flag it doesn't show any errors. My internet connection is stable and it does the same thing on multiple connections. I tried changing the XferCommand to curl, wget, aria2c, neither of which helped. I've disabled the download timeout, increased parallel downloads (it does the same thing, when I leave it at one), I've tried clearing the pacman cache, removing unnecessary big packages (which helped, but only because my pc had more chance to download everything in time until it borked itself) I've tried quitting every app and just staying at the pacman window, staring at it, but none of that fixed it. I also tried running paru instead of pacman, even though it just runs pacman as a part of the process afaik. I don't really know what to do anymore. Google doesn't show me anything.

Thanks in advance for any and all help and have a nice day.

throughput comes to a screeching halt.
What does your mirrorlist look like (and when using -v / --debug, what mirrors are being used)?
mirrors.kernel.org has recently flared up a lot (probably LLMDOS)

Have you tried running pacman while logged in to a root terminal ?
If not, CTRL+ALT+F2 , login as root and test.

Can you elaborate on this? You turned the router off *during* a pacman download? Because then either a) pacman download speeds craters while it times out on a connection or b) you are connected to a different network than you think you are and the download happily continues.

A couple things come to mind.

Just a sudden stop, no error, no nothing.

1) How long are you giving it?
If network bandwidth is saturated, perhaps this is causing an output pause?
Possibly try waiting longer?

2) What filesystem is this on?
Pacman checks for space. IIRC some fs are not able to be properly checked. If this is the case and you're out of space, perhaps this would cause a hang?
Although this wouldn't explain the eventual completion.

It also doesn't make sense pacman would freeze, then exit/halt without throwing some kind of error message.
Are you stopping pacman manually, which would account for the bd.lock?
