Description Davide Bolcioni 2005-01-03 11:27:35 UTC

Description of problem: when attempting 'yum update' with http_proxy
and https_proxy set, 'yum list updates' works but 'yum update' fails
with '[Error -1] Header is not complete' for all mirrors in
distributed mirrorlist. Unset *_proxy and it works fine; FC1 hosts on
the same network operate through the same proxy without a hitch.

Version-Release number of selected component (if applicable): yum-2.1.11-3


How reproducible: always.


Steps to Reproduce:
1. install FC1 on a gateway
2. install squid on the gateway
3. install FC3 behind the gateway
4. upgrade FC3 without the proxy up to before the RPM below
5. set *_proxy to address squid on the gateway
6. try 'yum update'
  
Actual results: [Error -1] Header is not complete for
selinux-policy-targeted-1.17.30-2.62


Expected results: update of the aboce


Additional info: the yum output is somewhat confusing

as it seems to be downloading the RPM instead of the header, and the
squid log confirms this:

Comment 1 Davide Bolcioni 2005-01-05 17:46:30 UTC

Sorry, my mistake. The gateway is multihomed and the value of *_proxy
was not correct; wget got it right because the appropriate value was
in /etc/wgetrc.

Comment 2 Davide Bolcioni 2005-01-05 17:53:30 UTC

Sorry again, too eager. Even with the correct proxy, new headers get
[Error -1] Header is not complete.

Comment 3 Seth Vidal 2005-01-05 18:06:07 UTC

does your proxy not support byte-ranges?

Comment 4 Davide Bolcioni 2005-01-07 11:13:25 UTC

Great suggestion: the squid.conf was too paranoid and overused
header_access, silently strangling byte range functionality. Allowing
through the appropriate HTTP/1.1 headers did the trick. Thank you very
much.
