"apt-get update" runs for 20 minutes...
Hi All,
First post, I've been stuck on a problem got 2 weeks now. When I run apt-get update on my Ubuntu 12.10 machine it hangs for 20 minutes on 'Reading Package Lists...##%' which on my Debian 6 server takes less than a second. My machine is quite powerful and I've been able to do most everything else; install steam, run TF2, music, videos, xbmc and so on... so I know it's working. I can't see any errors in logs that could explain this. So far my best lead is the ltrace and strace I ran to see where the time was being spent but I don't know how to diagnose further.
Any and all help appreciated!

The only time I've seen 'apt-get update' run slow is when DNS is down.
During the execution of 'apt-get update', are you seeing any timeout error messages in the output? If so, then this is definitely a DNS related issue! Can you paste the output of the command on pastebin?
Cheers,
tk.

Hi, I don't think it is DNS as my Debian server can do the same thing without issue. Also I think that it's done getting information from the web by the time it gets to the 'Reading Package Lists...' stage.
I'm sure I could prove this by removing all web sources and adding only the DVD for content, but I'm at work right now.
What is clear from the above output is that '_ZN11CommandLine11DispatchArgEPNS_8DispatchEb' & '_ZN12pkgCacheFile11BuildCachesEP10OpProgressb' are hogging ALL of the time. Making single call each and then taking around 900 seconds to finish. Why on earth could this be?
Thanks,
Noki

my entire apt-get update output
pastebin dot com slash 3ijrv3ji (cant paste links yet)
with the last step where it slows and takes 20+ minutes.
thanks again, any help diagnosing this is appreciated.

Hi All,
I've just run another apt-get update, this time with ltrace. It shows I've been able to get the time down from 33+minutes in my first post to around 25 minutes, mostly thanks to help in various forums, thanks again!
ltrace -c apt-get update:
pastebin dot com slash eyENvETS
This is the section that most interests me;
Also, I've just found a new error, my machine keeps needing to send error reports to Ubuntu which has only started in the last 2 days. It seems to happen when I use the Software centre to install things. Specifically it complains about aptd. I looked at the manpage and found a debug command which outputs:Code:% time seconds usecs/call calls function ------ ----------- ----------- --------- -------------------- 47.44 713.119059 713119059 1 _ZN11CommandLine11DispatchArgEPNS_8DispatchEb 47.07 707.538760 707538760 1 _ZN12pkgCacheFile11BuildCachesEP10OpProgressb 1.82 27.321004 53153 514 select 1.07 16.064317 297487 54 _Z6WaitFdibm 0.57 8.509646 607831 14 curl_easy_perform 0.50 7.568873 7568873 1 _Z10ListUpdateR16pkgAcquireStatusR13pkgSourceListi 0.39 5.889650 7464 789 _ZN6FileFd5WriteEPKvy 0.18 2.730817 65 41782 __umoddi3 0.17 2.564672 8116 316 write 0.14 2.047325 2252 909 _ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_i 0.14 2.041083 755 2700 isspace 0.13 2.022598 1335 1514 _ZNSs12_M_leak_hardEv 0.13 2.017244 2266 890 _ZN10pkgAcquire10WorkerStepEPNS_6WorkerE 0.05 0.718136 188 3818 _IO_getc 0.02 0.334594 1262 265 _ZN12pkgAcqMethod3RunEb
