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:

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

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

$ sudo apt-get clean

$ sudo apt-get update
