util-linux 的 dpkg 配置永不结束，没有错误

Question

我正在运行 Debian vanilla，但是同样的症状也发生在我身上，并且我找到了解决办法——我发布了这个答案，希望它能帮助某人从中恢复过来。

在 util-linux.postinst 挂起后，我编辑了提到的 postinst 文件以添加大量日志记录：

#!/bin/sh
set -e

LOGFILE=/root/log.file

echo "Environment: " >$LOGFILE
env >>$LOGFILE


echo "update-alternatives" >>$LOGFILE
update-alternatives --install /usr/bin/pager pager /bin/more 50 \
    --slave /usr/share/man/man1/pager.1.gz pager.1.gz \
    /usr/share/man/man1/more.1.gz

# We stopped shipping the 'pg' utility, so remove it as a pager
# alternative on upgrades from Stretch.
echo "update-alternatives remove pager" >>$LOGFILE
update-alternatives --remove pager /usr/bin/pg

# Automatically added by dh_installinit/13.1
echo "step 3" >>$LOGFILE
if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then
    if [ -x "/etc/init.d/hwclock.sh" ]; then
        update-rc.d hwclock.sh defaults >/dev/null || exit 1
    fi

if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then
    # This will only remove masks created by d-s-h on package removal.
    deb-systemd-helper unmask 'fstrim.timer' >/dev/null || true

    # was-enabled defaults to true, so new installations run enable.
    if deb-systemd-helper --quiet was-enabled 'fstrim.timer'; then
        # Enables the unit on first installation, creates new
        # symlinks on upgrades if the unit file has changed.
        deb-systemd-helper enable 'fstrim.timer' >/dev/null || true
    else
        # Update the statefile to add new symlinks (if any), which need to be
        # cleaned up on purge. Also remove old symlinks.
        deb-systemd-helper update-state 'fstrim.timer' >/dev/null || true
    fi

echo "step 5" >>$LOGFILE
if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then

echo "step 5.1" >>$LOGFILE
    if [ -d /run/systemd/system ]; then
echo "step 5.2" >>$LOGFILE
        systemctl --system daemon-reload >/dev/null || true
echo "step 5.3" >>$LOGFILE
        if [ -n "$2" ]; then
echo "step 5.4" >>$LOGFILE
            _dh_action=restart
        else
echo "step 5.5" >>$LOGFILE
            _dh_action=start
        fi
echo "step 5.6" >>$LOGFILE
        deb-systemd-invoke $_dh_action 'fstrim.timer' >/dev/null || true
echo "step 5.7" >>$LOGFILE
    fi
echo "step 5.8" >>$LOGFILE
fi
# End automatically added section
# Automatically added by dh_installsystemd/13.1
echo "step 6" >>$LOGFILE
if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then
    if [ -d /run/systemd/system ]; then
        systemctl --system daemon-reload >/dev/null || true
        if [ -n "$2" ]; then
            _dh_action=restart
        else
            _dh_action=start
        fi
        deb-systemd-invoke $_dh_action 'fstrim.service' >/dev/null || true
    fi
fi
# End automatically added section
echo "step 7" >>$LOGFILE

检查 /root/log.file 中的输出，我发现步骤 5.6 是阻碍因素。在那里手动运行 systemctl 命令也会导致挂起。快速谷歌搜索表明系统在没有 fstrim 的情况下可以正常运行（一段时间 - 这存在磁盘寿命问题，尤其是对于 SSD），因此我注释掉了所有 fstrim 命令，并dpkg --configure util-linux成功重新运行。

希望能帮助到你！
