Description E Lilley 2010-01-29 23:06:50 UTC

Description of problem:

Yum cannot download metadata when there only exists an IPv6 address for a DNS server in /etc/resolv.conf

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

yum-3.2.25-12.fc13.noarch
python-pycurl-7.19.0-4.fc12.x86_64

Steps to Reproduce:
1. Remove IPv4 DNS server address from /etc/resolv.conf
2. Add valid IPv6 DNS server address to /etc/resolv.conf
3. Run yum upgrade or suchlike
  
Actual results:

root@hostname:~# yum install somepackage
Loaded plugins: download-order, presto, refresh-packagekit
http://ftp.icm.edu.pl/pub/Linux/distributions/rpmfusion/free/fedora/development/x86_64/os/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
http://fr2.rpmfind.net/linux/rpmfusion/free/fedora/development/x86_64/os/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.

i.e. pycurl bales out for some reason.

Expected results:

Normal DNS resolution from yum, & by extension, from python-pycurl as well.

Additional info:

This may be either a yum-specific or a pycurl-specific problem.

Comment 1 Bug Zapper 2010-03-15 14:18:31 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle.
Changing version to '13'.

Comment 2 Felix Kaechele 2010-05-30 19:09:56 UTC

Same goes for a repo that has a DNS name that only resolves to a IPv6 address. Same error as above.

Comment 3 Jeffrey C. Ollie 2010-12-02 22:20:09 UTC

Reassigning to curl since pycurl is just a wrapper.

Comment 4 Kamil Dudka 2010-12-02 23:06:36 UTC

This was already fixed in curl-7.20.1-1.fc13.
