I had exactly the same problem. Whatever I did, I could get not to the
I opened a terminal, killed the updating process. I then ran
sudo dpkg --configure -a
to finishing configuring the package upgrades that hadn't completed.
This partially completed, but exited reporting errors. These errors were
being reported as /var/cache/debconf/lock was not released when the
update manager process was killed. Searching on launchpad I found the
simplest way to release the lock was to
sudo rm -rf /var/cache/debconf/*
sudo dpkg --configure -a
then completed without error. I was presented with a number of
configuration screens giving me the option to keep or replace a number
of configuration files (php, samba, rsnapshot, postfix etc)
Once this was completed I then reran apt-get to update, to ensure that
everything was updated, which also completed without error.
At this point I was confident to reboot and when I did I was able to
restart and log into 10.10
I had backed up everything before starting, and also cloned my 10.04
install on to an external USB drive using Clonezilla so restoring my
working 10.04 install wouldn't have been too hard. My internet
connection is quite slow at work and in the past I have had the update
process trip up on some packages that didn't download, so I was prepared
for potential problems in the process. However, I have read on this list
and other places to not restart the machine if there is a problem as it
maybe possible to rescue a seemly failed upgrade, which in this case
proved to be correct.
I would like to file a bug on this, but I am unsure of the best place to
do so. I have searched launchpad and I think I should file it against
update-manager, but I wonder if this is the correct package? Could
anyone confirm this, or direct me to the correct one?
