pacman -Syu very slow

descendent87 · 2009-08-10 20:19:10

Since the updates to pacman if I try doing

pacman -Syu

it is extremely slow (I typed it about 30 minutes ago and so far it has only refreshed the testing repo), however if I try

pacman -Syy

then it updates at normal speed and only takes a few seconds to finish

mokasin · 2009-08-11 10:58:04

Same here. But what does -Syy do? Can't find this option in the manpage.

It's the force option for -Sy it syncs even if the local database is up to date.

I've got the same problem, I hope it can be solved. It came up yesterday after a crash of my system (hardware error) while pacman was upgrading my system with a relatively big number of packages (epecially KDE), because I was on vacation before and my computer was at home.

Check if there is an lock , and just try to force refresh mirrors and upgrade. If i recall it right if arch was downloading and not installing yet it won't hurt

@TS: did you try to switch mirrors ? ( although this is strange behaviour )

firecat53 · 2009-08-12 15:16:10

I've also noticed this behavior -- it seems to happen when your local database is all up to date (ie there's nothing to sync). But I'm not entirely sure about that.....I just tried a pacman -Syy and it's doing the same thing. Maybe its more random than I thought. This is a new behavior since the pacman upgrade a week or so ago, I think. I've seen it both on x86 and x86_64.

The crash had no effect on pacman, though I did an force update after it, pacman needed too much time to sync. I can confirm firecat53's notice, that only local databases with all data up-to-date cause problems. In my opinion this is a problem of the new version of pacman, perhaps we can find a workaround here.

gabriel9 · 2009-08-12 19:48:48

I try:

pacman -Syu

Everything is fine, but when it offer me a update i pressed <y>, but nothing happen.
I try again:

pacman -Syu

Realy slow, stuck on CORE for some time. <Ctrl>+<C> is only option.
But:

yaourt -Syu

Works fine.

Lone_Wolf · 2009-08-12 21:10:27

I've had the same issue and ran "pacman -Sc" followed by pacman-optimize .
Pacman -Syu is now functioning normally again.

Samuel from beteigeuze · 2009-08-12 21:17:20

Unfortunately this doesn't help here, updating is very slow again.

Had tried switching mirrors but didn't work, tried pacman-optimize but nothing either. Just had another look at mirrors and have now noticed this is only happening on ftp mirrors, http mirrors are working fine

ThoughtMonster · 2009-08-12 23:21:15

Same thing happens here, pacman -Sy seems to hang in "Synchronizing package databases...".

Strange thing, if I uncomment XferCommand it works fine. Continues working fine even after I recomment XferCommand.

As descendent87 said, commenting all ftp mirrors, leaving the only the http mirrors uncommented seems to "fix" the problem.

R00KIE · 2009-08-13 20:41:25

I only have 1 ftp mirror uncommented and pacman seems to work fine, no delays, seems to be something else ... maybe a bad mirror, did you try opening the mirrors in your list with your browser to check if they open properly and fast?

TigTex · 2009-08-13 21:46:38

Do you have a lot of HDD activity during pacman -Sy ? (or -Syu -Syy... or anything that reads local database)
That behaviour appens to me in old low end pc's (slow hdd).

Not that I could say. How do I find out?

If -Syy works than it should be a problem of the FTP-Server. If I use only one it doesn't change anything.

SpeedVin · 2009-08-14 12:49:38

Hmm I got the same sittuation -Syu is slow but if I do -Syy and after this I do -Syu it's fast.

I've solved such a problem so:

http://pastebin.com/m4cabc2d

So I splitted for 3 different mirror list, and every mirror list contains just one line in it with the correct repository url.

AngryKoala · 2009-08-15 14:53:05

Try different DNS servers. http://www.dnsserverlist.org/ gives you 3 servers that are close to you.

mokasin · 2009-08-15 14:55:09

Sorry, I wasn't clear enough. I get the error that the pastebin id doesn't exist. So the link works in that way.

djszapi · 2009-08-15 21:57:28

I gave in the pacman.conf 3 different mirrorlist files, and each one contains just one line for the actually using repo, that's all I use german mirror.

guzz46 · 2009-08-16 00:12:46

i have a similar problem, its not the download speed of pacman thats the problem but it now takes about 5 seconds after finishing downloading 1 file to move onto the next file, which can take a long time if you happen to be downloading lots of small files.

This I solved with new/additional DNS.

why do we need so many threads about the same issue? I am tired of posting in all of them
http://bbs.archlinux.org/viewtopic.php?id=78238

I believe I fixed this issue : http://projects.archlinux.org/?p=pacman … ae80c5988d
so wait for 3.3.1
