Deadlock in APT with cdrom?

[Leonardo Macchia <macchia@students.cs.unibo.it>]

Hello.

I'm using a Debian Woody with apt version 0.3.17.
Sometimes during updating (dselect with method apt and sources.list pointing
to cdroms and local files) I think I get a deadlock situation:
just before asking "Yes" to update/install confirmation (after [I]nstall's
dselect option) or just before asking to replace cdrom, I see a blocking
situation; this is the process-tree (for the latter case):

15869 tty2     S      0:00      \_ sh /usr/lib/dpkg/methods/apt/install /var/lib/dpkg apt apt
15872 tty2     S      0:02          \_ /usr/bin/apt-get -f dselect-upgrade
15885 tty2     S      0:00              \_ /usr/lib/apt/methods/cdrom

"strace -p 15885" shows:

select(1, [0], NULL, NULL, NULL <unfinished ...>

That never unblocks... since all coditions are NULL. I usually "unblock" the
situation with a "kill -PIPE 15885" but I think this is not normal. :)

Thanks in advance, Leonardo Macchia.
