Hi, I will keep this bug open for a while, though. Yesterday I saw a checksum verification error from apt on experimental's Packages.xz so I made a snapshot. And... the issue was a big bunch of zeroes in the middle of the file.
I have seen a such thing once, some months ago, but back then it was exactly one sector of zeroes so I attributed it to some filesystem fsckage. Not so this time... it need a deeper inspection on the code which does concatenation&resuming, maybe something is weird there. But still, it always hits experimental, that's not normal. Regards, Eduard.
