[Pkg-xen-devel] Bug#787193: xen-utils-common: xen-init-list crashes with TypeError, renders reboots unfeasible after upgrade from wheezy to jessie

[gabriel at koumbit.org]

Package: xen-utils-common
Version: 4.4.1-9
Severity: important

This bug was already reported as #763102 and was brushed off because maintainer
says it implicates xend which is not there in 4.4 anymore. However, this
problem is present during upgrade from wheezy to jessie and means that reboots
are not possible without physical interventions.

As noted in #763102, during shutdown, we can see this message:


/usr/lib/xen-common/bin/xen-init-list
Traceback (most recent call last):
  File "/usr/lib/xen-common/bin/xen-init-list", line 70, in <module>
    d = DataSXP(p)
  File "/usr/lib/xen-common/bin/xen-init-list", line 52, in __init__
    s = SXPParser()(p)
TypeError: 'SXPParser' object is not callable

but after this, I get this error:

mount: / is busy.

it then results in the reboot process to hang after the line "Rebooting." and I
get messages each 2mins about the "reboot" task being stuck for more than 120s.


I found out a way to resolve this issue: by purging the xen 4.1 packages that
are still present, the error goes away and reboot works well again:

apt-get purge xen-utils-4.1 xen-hypervisor-4.1-amd64 libxen-4.1

maybe the 4.4 packages should conflict with 4.1 to ensure that both versions
are not present simultaneously?
