While upgrading libc6:amd64 (2.37-14), it stuck forever.

Expected Behavior

Should be able to upgrade

Actual Behavior

And I can see telinit u takes 100% CPU

A lot of people also having this problem:

I had the same issue, #11035 (comment) fixed it.

As far as I can tell if you don't have

[boot] systemd=true

The /run/systemd/system directory is not created and the tests in the postinst for libc fail:

    # Restart init.  Currently handles chroots, systemd and upstart, and
    # assumes anything else is going to not fail at behaving like
    # sysvinit:
    TELINIT=yes
    if ischroot 2>/dev/null; then
        # Don't bother trying to re-exec init from a chroot:
        TELINIT=no
    elif [ -n "${DPKG_ROOT:-}" ]; then
        # Do not re-exec init if we are operating on a chroot from outside:
        TELINIT=no
    elif [ -d /run/systemd/system ]; then
        # Restart systemd on upgrade, but carefully.
        # The restart is wanted because of LP: #1942276 and Bug: #993821
        # The care is needed because of https://bugs.debian.org/753725
        # (if systemd --help fails the system might still be quite broken but
        # that seems better than the kernel panic that results if systemd
        # cannot reexec itself).
        TELINIT=no
        if systemd --help >/dev/null 2>/dev/null; then
            systemctl daemon-reexec
        else
            echo "Error: Could not restart systemd, systemd binary not working" >&2
        fi
    fi
    if [ "$TELINIT" = "yes" ]; then
        telinit u 2>/dev/null || true ; sleep 1
    fi
