Bug Description

Binary package hint: debsums

I tried to execute "debsums -s" on six different machines running dapper on amd64 and I always got this error message:

Reading from filehandle failed at /usr/bin/debsums line 266, <SUMS> line 17.

and debsums exits.

Version of installed debsums package:
debsums 2.0.24

An strace reveals the culprit:

open("/lib/udev/devices/net/tun", O_RDONLY) = 6
read(6, 0x9e91e0, 4096) = -1 EBADFD (File descriptor in bad state)
Reading from filehandle failed at /usr/bin/debsums line 266, <SUMS> line 17.

Interestingly this particular file is only in bad state only on my amd64 machines (but that may just be a coincidence):
dapper_amd64:~ # cat /lib/udev/devices/net/tun
cat: /lib/udev/devices/net/tun: File descriptor in bad state

dapper_i386:~ # cat /lib/udev/devices/net/tun
cat: /lib/udev/devices/net/tun: Permission denied

However, in every case debsums should just report the offending file and should just go on.

the bug is fixed in debsums from hardy (2.0.34).
It correctly handles offending files (in this case /lib/udev/devices/net/tun)

debsums: can't check udev file /lib/udev/devices/net/tun (not a regular file)

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in Feisty.

debsums (2.0.30) unstable; urgency=low
  * Paranoia: only check regular files (not char special, pipe, etc).
