13.10 wont update, (nautilus/dropbox)

Ubuntu 13.10 is not supported any more, it entered end of life status almost a year ago.
I recommend that you upgrade to Ubuntu 14.04 (supported until 2019)
see https://wiki.ubuntu.com/Releases

Possible procedure:
1. create backup copies of your important files (in case something goes wrong)
2. issue the terminal command
sudo do-release-upgrade

If this fails with an error, please copy/paste the full message text into this question document that we have a chance to find the root cause.

Hello Manfred, thanks

This may be a simple remedy but I don't exactly know what I'm doing. There
are 76 processes running. CPU1 is at 100%
Here is the error message...
"Checking for a new Ubuntu release

I think you may have repied but I see no message
My problem has not been resolved

Apparently there is a process running that locks the package management system.

You can either reboot your system, or try the commands

sudo fuser -vvv -k /var/lib/dpkg/lock
sudo fuser -vvv -k /var/lib/apt/lists/lock
sudo fuser -vvv -k /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock

and then re-try

sudo do-release-upgrade

well I've tried the above commands
apt and dpkg killed them
the release-upgrade command still gets same response "unable to get exclusive lock"
the Software Updater status window isnt greyed out but still hangs "configuring nautilus-dropbox"
ofcourse I've tried rebooting.....

after reboot - authentication is required... is needed to run '/usr/bin/dropbox' as the super user.
What is that? Normal?

Ahhhh finally... all went swimmingly.
Nasty dropbox! but I suppose I have plenty more to learn and read.
Thank you very much for your help
