[t.van.der.plas]

Dear all,

when trying to update from 10.3.1 to 10.4.4, the update fails with the following message:

Execute command DEBIAN_FRONTEND=noninteractive LANG=C apt-get --assume-yes --show-upgraded --purge --list-cleanup --no-reinstall -o Dpkg:ptions::=--force-confdef -o Dpkg:ptions::=--force-confold -o Acquire::Retries=3 -o APT::Get::AllowUnauthenticated=true -t 'lucid*' install pp10.13.4-bootstrapper=10.13.4-ubuntu10.04.build1013111102.18
ERROR: write to xml_fd: Bad file descriptorAusgabe des ausgeführten Prozesses konnte nicht eingelesen werden: (Bad file descriptor).

any idea how to fix this?
