Comment 4 for bug 1383789

An examination of the outgoing HTTP requests for aptitude changelog vs. apt-get changelog shows that aptitude is missing a /pool in the URL:

No. Time Source Destination Protocol Length Info

(first half is `aptitude changelog`, second half is `apt-get changelog`)

Looking through the Debian -> Ubuntu patches for 0.6.8 vs 0.6.11, the lines

Apparently the new patch doesn't work?
