Linux version of Calibre, problems with Meta Data

[Nirf]

Hey, I used the windows version of Calibre and it worked absolutely flawlessly in every respect. Boy was I impressed, so I'd like to shout out a thanks to the developer of calibre, Kovid Goyal. Fantastic work. I'm now using the Linux version, and it still works well with just one hiccup. The metadata and cover image retrieval features don't work well (even though I'm signed up at the websites and all that). Here are the error messages I get in both cases:

Could not fetch ISBNDB metadata. Error: [Errno socket error] (-2, 'Name or service not known')

and

Detailed traceback:

for the cover image. Help, suggestions? thanks in advance.

I am having the same problem as the original poster. I have recently built a new PC and put a fresh Linux install on it. Calibre on my old PC worked fine on 64bit Linux. Now it works ok, but it gets the:
Could not fetch ISBNDB metadata. Error: [Errno socket error] (-2, 'Name or service not known')
error when I try to grab metadata.

I took a look at the ticket for it. I am not using a proxy. Here is the output of calibre-debug -c "from calibre import browser; print browser.open('http://google.com').read()"

Traceback (most recent call last):
File "/tmp/init.py", line 45, in <module>
File "/home/kovid/work/calibre/src/calibre/debug.py", line 150, in main
File "<string>", line 1, in <module>
AttributeError: 'function' object has no attribute 'open'
Segmentation fault

Is there anything I can do to get the metadata downloading working? Either way, thanks a lot for Calibre. I'm a happy user.

it should be

calibre-debug -c "from calibre import browser; print browser().open('http://google.com').read()"

Here is the output:

$ calibre-debug -c "from calibre import browser; print browser().open('http://google.com').read()"

that error indicates name resolution is not working on your machine
