Connecting to archive.ubuntu.com takes too long

Yesterday, I got one error with “apt-get” command in one of our server which has Ubuntu 12.04 OS. After the Y/N confirmation of apt-get installation command the server went to un-responded state for 4-6 minutes.
Error details are pasted below:

0% [Connecting to archive.ubuntu.com(2001:67c:1360:8c01::1a)]

Solution:
I figured out the problem. I had to disable IPv6 connectivity, as The Lord Of Time pointed out.
Running the following command in Terminal tells if IPv6 is enabled or not:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6 0 means its enabled 1 means its disabled

To disable IPv6 from within Terminal, enter the following and reboot:

echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

After boot, re-run the first command(cat...

My guess is, that the problem are DNS requests timeouts. Try ... turning off the UseDNS option on the server you are connecting to.

The server log pretty much confirmed this (so well done for posting it :).

debug3: Trying to reverse map address 10.0.2.2. # ^^^ spends a lot of time after this line

Looking at man sshd_config:

UseDNS Specifies whether sshd(8) should look up the remote host name and check that the resolved host name for the remote IP address maps back to the very same IP address. The default is “yes”.

Note that this is pretty much pointless. The check does not kill the connection. If it doesn't pass, it just logs a finger-wagging message:

Jul 9 05:43:00 brick sshd[18971]: Address 200.41.233.234 maps to host234.advance.com.ar, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

which only serves to generate scary false positives for users with incompetent ISPs.

OK, so how can this cause a...

Hello @lorddanielon - Greetings!

Thanks for reaching out! I'd like to help

To assist you better I need to know the operating system on your computer & the printer model that you have. Please do let me know the same.

Alternatively, try the steps mentioned below and check:

· First, unplug the USB cable from the printer if present.

· Go to Control panel – Programs and feature – Select all the HP LaserJet printer entries and uninstall them.

· Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.

· Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.

· Under print server properties, go to drivers - remove any entry there as well.

· Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

· Restart your computer.

I’m working through the “Getting Started with Docker” tutorial. I’m working within a corporate network. I followed the troubleshooting hints and edited /var/lib/boot2docker/profile in my default docker machine to configure it for the corporate network proxy. That worked and allowed general access beyond the corporate network.
However, when I reached the “Build your own image” step in the tutorial I the apt-get of archive.ubuntu.com is failing during the build saying that it cannot connect. I see that this is an IPv6 address and perhaps that is the issue. I’ve read through the docs I can find on IPv6, but have not been able to figure this out. This seems like it may be a general issue, but I could not find a solution in the forums. If I’ve missed it, please point me in the right direction.

Expected behavior

The build should succeed and apt-get should be able to connect with archive.ubuntu.com.

Actual behavior

The build fails because apt-get cannot...

While connecting to remote server, the connection phase (after verifying the password, before displaying window with contents of remote folder) seems to take too long (more than an hour sometimes). When connecting to the server with putty, I get connected in cca 2 seconds (using the same hostname, port, protocol, login, password). What more, I'm unable to kill WinSCP process in Process Explorer. There is no visible window for this process (getting this info also via ProcExp). This issue is pretty recent, but I don't remember upgrading WinSCP at the time of change (also, I haven't changed any connection settings, which is proved by being able to connect with putty).

- WinSCP version: 4.2.9.938
- OS: Windows XP, SP3
- SFTP
- I use GUI (Commander)
- steps: I press "Login" button, small window appears (text running) for a short period of time, then disappears and nothing happens for a long time. Then the commander-like window appears and I can...

When I was trying to install "git" in bash, it always had a problem connecting to ubuntu's servers. Yes I have internet, Yes I can browse using a browser. I can pull up webpages I've never been to. I can ping an ip address etc etc etc. I also went directly to the file it was attempting to download and was able to download the deb it couldn't find. I even did an apt-get update. Still can't connect to ubuntu servers. It has to do with the bash itself. This is very upsetting because I've seen videos with other people being able to install git and other repositories just fine. If anyone had this problem or can help me fix this that be great!

I included this also

Hi there,

it seems like the configuration of your wireless adapter in your computer does not match the configuration on your wireless access point (router, hot spot, etc...).

Try the following: (instructions for Windows 7. It may vary in other Windows OS but basically is very similar...)

1. Right-click on the network icon on the task bar (right side, close to time/date) and select Open network and sharing center

2. On the Control Panel Home (look on the left side panel), select Change adapter settings

4. Right-click on the appropriate wireless adapter and select Properties

5. Click Configure...

6. Select the Advanced tab (2nd tab to the left)

Now you have access to the advanced properties that control the way your computer communicates with the router. To make it simple: they must talk the same language. There are many potential problems here but you are looking for something specific: Channels. Locate that information in the...

HOLY FUCK I JUST WROTE THE BIGGEST FUCKING WALL OF TEXT GIVING DESCRIPTIVE STATEMENTS ABOUT MY ISSUE/ANSWERING THE QUESTIONS FOR THE INFO YOU NEED TO HELP ME AND THEN 1 LITTLE MISSCLICK AND IT'S ALL GONE. Christ I'm mad.
I'm going to breeze through it this time. Ask me questions if I don't give enough info.
So I first installed the stand alone .jar and .bat server files and it wouldn't let me join straight away, I got several different weird errors and then I got in, same with my friend. Then I wanted to install some plug-ins and shit went down. Every time I tried joining I would get a different weird error message, and so I redownloaded the software/tried without plug-ins and the problem persisted. I don't get different errors anymore, Just the same one it seems. I don't have the server.logs from the deleted/uninstalled servers. I don't know if it's related but since trying to use Bukkit I also have been having issues signing into minecraft, maybe...

UPDATE : Just wanted to say that I've finally managed to fix my problem - It was the router firmware ! Since I've updated it, the problem didn't come back, and my wireless connectivity is finally established right away when I turn on my laptop. I've thought to post the solution here so it can maybe help someone with the same problem. Here's a link on how to do it in case someone doesn't know (hope links are allowed here):


http://www.wikihow.com/Update-Router-Firmware

I've also switched to Windows firewall , idk if it also helped but it's kinda easier for me now

UPDATE NO 2: ok i know it's been a long time since I've posted this and i still have the same laptop, so here is another update. The solution mentioned in my previous post helped me the most, but unfortunately not on long term. However, I was lucky to find out there is a simple trick almost everyone with wifi connection problems can use, and that is connecting with your smartphone. To do so, you will...

The server at google.com is taking too long to respond. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Nightly is permitted to access the Web.

This error solution is common for windows 7,windows 8,windows 8.1,windows 10 also and this error is occurring while try to access the following websites like that google,facebook,youtube,twitter.

I have a Ubuntu 11.10 server that I just installed fresh. Now if I try to do anything with apt-get, it tries to connect to archive.ubuntu.com .. It stays at [Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase for like 2 minutes, after which it actually starts to communicate and download stuff …

Eventually it always connects, but in waits at the [Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase everytime for like 2 minutes !

I didn’t have this problem previously on Ubuntu 11.10, right after reinstalling the OS ..

Any ideas on what the problem might be ?

Solution
I solved this on 12.10 by editing /etc/gai.conf and uncommenting the line:

This lets you keep IPv6 enabled, but sets the order of precedence to prefer IPv4 over IPv6.

I had a server recently start having serious problems with connections of all types, at least when IPv6 was involved. I use IPv6 at home and ssh access took a significant amount of time to make a connection. Then when I tried to do apt-get update from the server it would fail with a message like this:

$ sudo apt-get update [sudo] password for matt: 0% [Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] [Connecting to security.ubuntu.com (2001:67c:1360:8c01::1...

It would sit there and take forever without making any progress. Sadly, the Ubuntu docs aren’t much help unless you’re using Ubuntu 8.04 or older (I refuse to link to them which will only add to their credibility).

A workaround is to disable IPv6, but really you should take the time to fix the problem, since it is the way of the future. In my case I’m sure it’s routing related, and hopefully my server provider can resolve it. Until then, I do this:

Check if IPv6 is enabled by doing ifconfig and...

Bumping to ask related question --

I've been trying to back up my DVDs to small-size MKVs, but I think the encoding speed is getting a bit slower, probably because I'm using settings like Exhaustive Motion Esitmation with a 64px range (I used to use Uneven Multi-Hexagon) and 9/14 Reference/B-Frames for the anime...

Anyway, what I'd like to know is, would it be a good idea to buy more RAM to speed up encoding?

OS: Kubuntu 9.04 Jaunty
CPU: Intel Core Duo E8400
RAM: 2GB
Swap Memory: 4GB
Video Card:GeForce 9800GT PCI-E 512MB
SysInfo output is attached of you want more detail.

Another related question: Will I need to change my swap memory from 4GB to 8GB? If so, is there a way to do resize the partitions without losing data?

Edit: I just noticed the guide for resizing partitions without losing data on the GParted site...

Thanks for the suggestion about wireshark ! I remember putting data analyzers on the wires many moons ago - things have moved on haven't they.. Anyway I did a capture of the packets for both the BIG file that "hangs' and the small file that doesn't. Not sure what to look for though. Ideas ?

Separately, more progress - turns out that the big file download WILL terminate, 15 minutes later, though.. Basically, it gets the file.. hangs for 15 minutes and then does some sort of retry and then terminates.. Here's the output. Note that delay between 11:24 when to all intents and purposes its got the file and it just hangs until 11:39 when it does a cursory retry and terminates to the $ prompt.
