Ubuntu 13.10 Beta testing issues in upgrading few packages

I upgraded to Ubuntu 13.10 Beta couple of weeks back. Dist-upgrade exited with error. I didn't give attention to the error that time. Since last week i noticed that some package upgrades failed. Trying to troubleshoot it i found that initscripts installation is failing with error - cannot create cannot create /var/log/dmesg: Is a directory. To my surprise there was directory /var/log/dmesg and under that there were some files like boot-repair.log and one directory each of the partition i had (eg: /var/log/dmesg/sda). Since this was a test setup i went ahead and moved the directory sudo mv /var/log/dmesg /var/log/dmesg.old

Then did this: sudo apt-get update && sudo apt-get dist-upgrade

Voila! all packages installed correctly. Note that while i had around 64 packages waiting to be installed (and unable to install) because of this issue the system was fairly stable and didn't face any issue operating it normally. I did not use it heavily though
