cant dist-upgrade, broken repository ??

[Fred Schaer]

Hi,

Trying to dist-upgrade, I have a strange problem : apt is trying to 
upgrade the package "keep", but if fails with :

Err http://fr.archive.ubuntu.com edgy-backports/main keep 
0.4.0-0ubuntu2~edgy1
  404 Not Found
Unable to retrieve 
http://fr.archive.ubuntu.com/ubuntu/pool/main/k/keep/keep_0.4.0-0ubuntu2~edgy1_i386.deb  
404 Not Found

(I updated the package list, yes)

It seems to me there's effectively a problem since there seems to be no 
such package in that place, but rather a 
http://fr.archive.ubuntu.com/ubuntu/pool/main/k/keep/keep_0.4.0-0ubuntu2_i386.deb 
file (missing "~edgy1" in the file name...)

Also, I'm surprised the web page appears in firefox with a orange 
company logo ?
Any advice ?

Cheers
