[Solved] Long Pause Between Package Downloads

I have recently installed Arch on my laptop and ever since it's first boot from installation, pacman has been acting strange. When I tell it to install a package, there is a long pause before each package starts downloading. It's not my internet connection, because when the downloads finally start, they go at normal speeds for my network.

Any ideas?

Thanks!

Try this: tell pacman to install something, abort when it asks you y/n and try installing again - is it still slow? Maybe it's just figuring out dependencies etc.

Tried it. That's not it. The slowness seems to start after I hit "y". I love Arch but this problem is making it almost unusable. And if this helps: The "slowness" is not present when I install a local file.

Re: [Solved] Long Pause Between Package Downloads

Are you using any XferCommand in pacman.conf?
Post the output of 'pacman -S --debug <whatever>'.

By <whatever> I mean a non-local package, not something you have already installed and you reinstall it. You need to download something, OK?

The output was so long that some of the first stuff was pushed out of the buffer. Here's what I got: http://pastebin.com/download.php?i=pcvVgZx8

You can redirect output e.g.

pacman --debug -S qt > foo.log

Re: [Solved] Long Pause Between Package Downloads

Long pauses between downloads usually means one of:

a) you're using an ftp server which is misbehaving
b) your DNS server is slow as hell

Re: [Solved] Long Pause Between Package Downloads

I agree with falconindy. Looks pretty clear it's some problem during the download stage.
You can isolate the problem and use cURL to debug the download stage:

url=$(pacman -Sp linux | tee /dev/stderr)
curl --verbose "${url}" -o /dev/null

It keeps timing out... couldn't download the file from a web browser either. Got the above response the 6 times I tried it.

Could it have anything to do with breach at kernel.org?

I'll try some different mirrors. Do you know any good US ones that are usually well-kept?

mirrors.kernel.org and mirrors1.kernel.org are not working right now, presumably under maintenance after the breach.
Pick a mirror here: https://www.archlinux.org/mirrors/status/

Re: [Solved] Long Pause Between Package Downloads

Is there a specific process to change mirrors? I commented out all mirrors except http://cake.lib.fit.edu/archlinux/, but my output of

url=$(pacman -Sp linux | tee /dev/stderr)
curl --verbose "${url}" -o /dev/null

still is

03:16 PM >> url=$(pacman -Sp linux | tee /dev/stderr)
[url]ftp://mirrors.kernel.org/archlinux/core/os/x86_64/linux-3.0.1-1-x86_64.pkg.tar.xz[/url]
 >>  curl --verbose "${url}" -o /dev/null

Why is it still trying to connect to kernel.org?

Did you do a 'pacman -Syyu' ?

Re: [Solved] Long Pause Between Package Downloads

If the above doesn't work, post your pacman.conf and your mirrorlist.
