Comment 8 for bug 1733591

I'm attaching a debdiff including the results of my own investigations into the failing autopkgtests. This gets a lot farther than before, but:

- on s390x 'kopano-admin -l' fails with an error because there is an endianness bug in kopanocore:
Wed Nov 22 04:45:22 2017: [warning] Object not found unknown user "匀夀匀吀䔀": 匀夀匀吀䔀
That string is:

$ echo '匀夀匀吀䔀' | iconv -f utf8 -t ucs-2le
SYSTE
$

and that's not a regression so is ignorable.

- on arm64 and ppc64el, kopano-dagent exits 75 instead of 0. I don't know if this is the reason, but I see the following denial in dmesg:

[ 567.593536] audit: type=1400 audit(1511327924.317:69): apparmor="DENIED" operation="mknod" profile="/usr/sbin/kopano-dagent" name="/usr/share/kopano-dagent/python/wraplogger.pyc" pid=9977 comm="kopano-dagent" requested_mask="c" denied_mask="c" fsuid=0 ouid=0

creating a .pyc file with mknod() is obviously crazy. I don't know whose bug this is.

aa-disable /usr/sbin/kopano-dagent lets the testsuite finish, so this evidently is the cause of the kopano-dagent failure.

Since this is a regression on ppc64el, and I didn't get to the bottom of it, I didn't bother testing on amd64/i386.
