[Piuparts-devel] Bug#701150: debsums falsing

[Dave Steele]

package: piuparts
severity: normal

While looking at the piatti piuparts report Andreas pointed to today,
I noticed that failures are racking up for debsums modifications.

The debsums man page, under Caveats, says that files which have been
replaced by another package may be erroneously reported as changed.
Multiple ownership can cause a false. It seems that a significant
portion of new failures are for debsums, and a significant portion of
these fall in this case.

I've seen this with dpkg diversions as well:

I believe that debsums should not report failures for modified files
which are owned by multiple packages, or are subject to diversion.
