Bug#558014: sasl2-bin: doesn't return from /etc/init.d/saslauthd start -> postinst script hangs

[Dirk Dike]

Package: sasl2-bin
Version: 2.1.22.dfsg1-8+etch1
Severity: critical
Justification: breaks unrelated software


I ran an apt-get update after not using my machine for > 3 months, which
updated (or installed) the package sasl2-bin that appears to do a
/etc/init.d/saslauthd start at the end of the postinst script at
/var/lib/dpkg/info/sasl2-bin.postinst. The code there is the following:

# Automatically added by dh_installinit
if [ -x "/etc/init.d/saslauthd" ]; then
        update-rc.d saslauthd defaults >/dev/null
        if [ -x "`which invoke-rc.d 2>/dev/null`" ]; then
                invoke-rc.d saslauthd start || exit $?
        else
                /etc/init.d/saslauthd start || exit $?
        fi
fi

However, that "hangs" like this:

# /etc/init.d/saslauthd start
saslauthd[28763] :main            : num_procs  : 5
saslauthd[28763] :main            : mech_option: NULL

saslauthd[28763] :ipc_init        : listening on socket:

saslauthd[28763] :have_baby       : forked child: 28765
saslauthd[28763] :have_baby       : forked child: 28766
saslauthd[28763] :have_baby       : forked child: 28767

This can only be halted by Ctrl-C, which also aborts the apt-get update.
After this, apt-get requires a "dpkg --configure -a" which tries to
execute the postinst script again and leaves you at the same problem.
This did, in effect, break apt-get for me, since I could not use it
anymore before resolving sasl problem

The only workaround i found was to insert "exit 0" at the top of the
postinst script.
