There are loads of similar traceback message saying the documentation build
has failed to retrieve some URL, like this:
```

```
This is clearly policy violation and should be patched.
This issue is found during the QEMU build on ppc64el machine for the armel
architecture, and it extremly slows down the building
process likely due to URL access timeout.
As a result, the URL access timeout took the whole night and the doc build is
not yet finished by a half.
Well, I guess I will have to wait for two or three days to see the discussed
armel segfault in qemu with this problem unfixed.
