Hi there,

can you provide details of how the upgrade was run and also which releases were being upgraded from and to?

If possible a full history of installed packages may help me to figure out why the upgrade failed by attaching /var/log/dkpg.log* to the bug report and the currently installed packages using

dpkg -l

thanks.
