I'm a Archlinux user. I have had trouble in pacman for 2 weeks. And I can't decide it's the problem of the network or pacman.

I use virtualbox and have some virtual archlinux machines. Since last week in the office, whenever I run "pacman -Syu" I always get the "network is unreachable" error. I can ping the web address, I can ping the ip, I can browser the mirror sites and download the files. But whenever I run "pacman -Syu" I got the "network is unreachable" error!

Then I copied these virtual machines home and install them on my own virtualbox, "pacman -Syu" works without any error. I copied the vdi files back to office, got the same "network is unreachable" error. I copy them home, worked flawlessly...

It's driving me crazy, I have no clue where things went wrong.

I was so careless, there is nothing wrong about the virtual machines. The problem was the network configuration on the host machine. Please delete this post if its being misleading.

Can you download with wget? It might be that your browser has found a proxy server that the command line doesn't know about. – Paul Jul 30 '13 at 9:14
I didn't install Guis. Just base system. Sorry I did't make it clear that I browsered and downloaded the files on my host machine. Your question reminded me. I tried downloading use wget and failed and I can't connect to sites using links. Links hangs on "making connection" – user1960581 Jul 30 '13 at 9:37
So where did you do the ping from? – Paul Jul 30 '13 at 10:06

I did the pingings from the virtual machines. I think that was what kept me think it was the virtual machine that was malfunctioning. – user1960581 Jul 30 '13 at 12:38
