I'm going nuts here. Perhaps I'm just an idiot. I have a remote server colocated in a data center. I initially built the server on a local network and then dispatched it to the facility. I currently have remote access via SSH. This server has been running for over 6 months without any problems that I know of. I feel that I have exhausted my results on Google and SE so now I turn to you for help.

Here is some troubleshooting information I have gathered:

  1. Last few lines of strace. I can provide more if needed:

    0% [Waiting for headers]) = 25aders]", 25
    select(6, [5], [], NULL, {0, 500000})   = 0 (Timeout)
    rt_sigprocmask(SIG_BLOCK, [WINCH], [], 8) = 0
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    0% [Waiting for headers]) = 25aders]", 25
    select(6, [5], [], NULL, {0, 500000})   = 0 (Timeout)
    rt_sigprocmask(SIG_BLOCK, [WINCH], [], 8) = 0
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    0% [Waiting for headers]) = 25aders]", 25
    select(6, [5], [], NULL, {0, 500000})   = 0 (Timeout)
    rt_sigprocmask(SIG_BLOCK, [WINCH], [], 8) = 0
    rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
    0% [Waiting for headers]) = 25aders]", 25
    
  2. A thread suggested that MTU or network may be the problem:

    root@ubuntu:~# ping -M do -s 1472 us.archive.ubuntu.com
    PING us.archive.ubuntu.com (91.189.91.26) 1472(1500) bytes of data.

  3. Perhaps its my sources.list? Well I thought that too... :

    ###### Ubuntu Main Repos
    deb http://us.archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse
    deb-src http://us.archive.ubuntu.com/ubuntu/ xenial main
    
    ###### Ubuntu Update Repos
    deb http://us.archive.ubuntu.com/ubuntu/ xenial-security main restricted universe multiverse
    deb http://us.archive.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse
    deb http://us.archive.ubuntu.com/ubuntu/ xenial-proposed main restricted universe multiverse
    deb http://us.archive.ubuntu.com/ubuntu/ xenial-backports main restricted universe multiverse
    
  4. IPv6 has been disabled on this server as per a suggestion.

  5. I have tried rebooting the server multiple times.

  6. apt-get clean does not solve the problem.

  7. Tried switching to ca.archive.ubuntu.com, no luck.

  8. I have requested a different public IP address from a different subnet to assign to the server. No luck.

  9. Other Ubuntu servers in this data center update without a problem.

So at this point the only solution I can come up with is to reinstall the operating system. This is a production web server with a small mysql database. Everything is backed up so it wouldn't be a problem to rebuild it. Just time consuming and quite disappointing.

This may be old but i had a same issue and fixed it like this:

$ sudo apt-get clean
$ cd /var/lib/apt
$ sudo mv lists lists.old
$ sudo mkdir -p lists/partial
