Hello Arnaud, thanks for taking the time to file this bug report and
work with us to make Ubuntu better.
This problem happened because mysql wasn't running when you started the
upgrade. Please try starting mysql and then finishing the upgrade with
sudo apt-get -f install
Closing as Invalid.

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a regular (non-security) bug. I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross
