Subject: perl: Fails to complete unpack during installation
Date: Mon, 18 Oct 2010 10:33:57 +0100
Package: perl
Version: 5.10.1-15
Severity: serious
Justification: Breaks installation

While dist-upgrading my system today, the perl package failed to unpack/configure 
(transcript below) and hung for over an hour until I killed the dpkg process.  After 
running "dpkg --configure -a" and "apt-get -f install" the package then continued to 
configure correctly.  It looks like it was somehow stuck between unpacking and 
configuring.  There was no response in the terminal to any keys (I tried hitting enter, 
but there was no response to the input, so maybe apt-get was doing something odd with 
termios if this wasn't a deliberate action by the perl maintainer scripts).

Looking as the ps listing (below), it looks like dpkg was being run on pts/2 which 
wasn't an open pty in any virtual terminal while apt-get was run on pts/1.  That's not 
typical, and may be the cause of the problem if perl was waiting on input due to a 
conffile change or debconf interaction.  The ps listing doesn't indicate any debconf 
usage though.

I'm afraid I can't give much more detail about the issue.  This may well not be a 
perl-specific bug if perl's pre/postinst isn't doing any messing with ptys.  In this 
case, it may be a bug in apt-get and/or dpkg.


Regards,
Roger

I used aptitude to upgrade three Debian testing workstations this 
morning, and ran into this obviously related issue on just one of them:

Once I got some time to deal with this I proceeded with the upgrade to 
perl (et al). I tried first on the initial system with no error, and 
then on 18 other systems -- again with no error.

These are all Debian GNU/Linux initial Squeeze install with repositories 
now set to testing, with absolutely no "outside" software installations. 
They are slightly divergent in configuration but largely the same with 
Xfce as the DE on all systems.

I'm sorry for the noise. I thought I was going to run into problems when 
I proceeded with the upgrade. (Don't know why -- probably lack of coffee 
or brains or both.)

I hope this information can be of some small help.

This is very weird. No, the maintainer scripts of the perl package
certainly don't mess with ptys in any way and actually do nothing at
the unpack stage of an upgrade. There are no conffiles and no debconf
usage either.

It looks like the different ptys for dpkg and apt-get are normal behaviour
for apt-get.

I take it /var/log/apt/term.log and /var/log/dpkg.log don't give any clues?

How did you obtain the process listing? Is it possible that it's missing
some maintainer script processes forked by dpkg?

The package seems to work for other people (10 days in unstable without
other reports) and the changes in 5.10.1-15 seem unlikely to cause
something like this.

My best guess is that this is either a problem with your system or some
corner case in apt-get / dpkg interaction but this is all just handwaving.

Tagging as unreproducible, let's wait a while for any other reports. The
package just migrated to squeeze so there should be plenty of people
upgrading in the next few days.

Now that we've seen 5.10.1-16 migrate to squeeze too after ten days in
unstable and no other reports of anything like this, I think it's clear
this is not an issue with the perl package.

I'm downgrading the severity so that RC bughunters can concentrate on other
things. TBH, I don't see much point in keeping the bug open at all.

Roger, please let me know if you're OK with closing this or if you want it
reassigned somewhere else. Personally I doubt the dpkg or apt maintainers
can do much about it either.

Yes, it's likely an apt/dpkg issue.  I'll reassign it to apt.


Thanks,

Hi Roger,


How APT is calling dpkg isn't changed magically for different packages and
packages have no real influence on it either (beside their depends of course).
So it should be the same problem for all users and all packages…

That dpkg seems to stop at unpack suggests more some sort of hardware
problem - especially now that dpkg does enormous amounts of fsync's.
So the changes are even higher than before that dpkg indicates a dying
harddisk - or have at least a tea break while waiting for the fsync to
complete which can take a while if you have other disk activity at the
same time.

I can see a lot of noise in ubuntu's launchpad about that [0].
And the debian buglist of dpkg is in no way better about the fsync's.


The bug is unreproducible and in its state untriageable, so i see
little point in reassign it to dpkg or keeping it open in general.
I am therefore closing this bug, with the strong suggestion to
check your harddisk(s) for near-death symptoms!


Still, thanks for your report &
good luck with and for your harddisk,
Best regards

David Kalnischkies

Thanks, looks pretty unreproducible, and it's most likely it is the dpkg 
sync issue already reported.

I'm fairly sure the HDDs are all fine--but it may have been the case 
that a USB pendrive or something may have been plugged in or something.



Thanks,
Roger
