I just checked here and it seemed to work. Either a dev noticed it already, or I got lucky with my mirror:

I forgot to ask: if it is a mirror issue, can you post the ones you hit?

Comment 3 Emmanuel Andry 2011-05-15 15:45:06 UTC

I use fetchcommandwrapper, so it's not easy to see the culprit, but those have wrong checksum :

http://trumpetti.atm.tut.fi/
ftp://ftp6.uni-erlangen.de

And those seems not to have the file :

Yep, the one that I have matches the manifest:

  $ md5sum /usr/portage/distfiles/ufoai-2.3.1-data.tar
  11468144bc00618c38667eec04b12a4a  /usr/portage/distfiles/ufoai-2.3.1-data.tar

But those two, at least, don't:

  $ md5sum trumpetti.atm.tut.fi/ufoai-2.3.1-data.tar 
  193ccc2e5e7f290198408fa03804ae53  trumpetti.atm.tut.fi/ufoai-2.3.1-data.tar

  $ md5sum ftp.uni-erlangen.de/ufoai-2.3.1-data.tar 
  193ccc2e5e7f290198408fa03804ae53  ftp.uni-erlangen.de/ufoai-2.3.1-data.tar

(but they match each other?)

Comment 5 Emmanuel Andry 2011-05-15 16:46:06 UTC

Strange it's not a compressed tarball.
Is it on purpose ?

Probably. Audio, video, and graphic data are already compressed with algorithms that work better than gzip, bzip, etc. Trying to compress them again would likely make the result larger.
